As the appointment line is long, Phineas and Ferb build a pet grooming contraption during the wait. While at Slushy Dawg, Doofenshmirtz spots Perry at the vet and goes to antagonize him. After being mistaken for a temp vet doctor, Doofenshmirtz sees an opportunity to chip Perry as a "freebie" evil plot.

"Lord of the Firesides"

James Kim

Oscar Lemus

Dodo Kitcharoen & Ryann Shannon

The Flynn-Fletchers takes a cruise to see the Tri-state Aurora, but cloud cover threatens to ruin the spectacle; Phineas and Ferb use clown balloons full of helium to lift the ship above them. Meanwhile, Doofensmhirtz brings Vanessa there as his supposed "break from evil"; Doofenshmirtz uses a "travel-size-inator" to shrink and steal various items around the ship, and Perry is sent to stop him; Major Monogram's aunt Olga and his son Monty are also aboard. As Vanessa and Monty begin to reconcile their relationship, Doofensmhirtz and Perry are shrunk and they fight. The inator misfires, shrinking both the balloons to bring the ship down, and the clouds so the Aurora is visible. This thwarts Candace's attempt to bust the boys, and as Doofenshmirtz reverses the shrink effect on himself and Perry, he is arrested for "bringing a pet on board". Isabella leads a Fireside Girls meeting to determine what cupcake flavor to bring for the Annual Fireside Cupcake Jamboree since Ms. Feyersied cannot make it. Perry has to ensure that Doofenshmirtz renews his license to conduct evil business in the proper fashion, and O.W.C.A.’s business license too. The Fireside girls reach an impasse over whether to bring vanilla or red velvet cupcakes, and they descend into chaotic disarray. Doofenshmirtz struggles through an evil assessment, Perry renews O.W.C.A.’s license, and Doofenshmirtz returns home, turning off his accidentally turned on "uncooperate-inator". This stops the girls' violence and they agree with Isabella's compromise.

As Phineas and Ferb take Isabella for a ride on a space-faring giant pogo stick, Candace gets suits of herself made from Buford's collection of life-sized molds, aiming to disguise Linda to confuse the "force" that ruins her busting plans. Doofenshmirtz's "Leftover-Revive-inator" has made his potato salad sentient and hostile, so Perry works to help him stop this. Candace "tests" her hypothesis with Buford. As Stacy and the other kids don Candace suits, Candace cannot find Linda amongst the disguised Candaces. Doofenshmirtz's inator misfires onto a stray Candace suit, and the potato salad monster launches the boys' pogo stick into orbit, ruining her busting plan. The sentient suit has a cliffhanger ending. As Stacy learned of Perry's dual identity secret last summer, Perry shows her an instructional video on how to deal with the knowledge. Candace and Stacy serve food to a symposium of doctors and scientists, which Doofenshmirtz attends and takes a "tag and bag" challenge with Doctor Diminutive. When Perry is captured by the doctors, Stacy gives chase, and with Monogram's cognizance, she uses her particular set of skills to break into L.O.V.E.M.U.F.F.I.N. headquarters and rescues Perry from being executed by hippopotamuses, receiving a fedora from him as a token of his gratitude.

Phineas and Ferb leave Isabella, Baljeet, and Buford to build something cool while they are with Linda; Candace decides to try and bust them. Meanwhile, Doofenshmirtz turns himself into a hideous moth, damaging Perry's hat such that he seeks a haberdasher to fix the microchip inside to avert an O.W.C.A. security breach. The three kids decide to combine their efforts to produce something impressive enough for Phineas and Ferb. Doofenshmirtz breaks into the haberdasher's office, and Perry defeats him by using a teleporting hat to obtain a laser gun from Doofensmhirtz that turns him back to normal. A misfire from the haberdasher turns the kids' invention into a moth that flies away before either Isabella can show Phineas and Candace can show Linda. Guest star: Alan Cumming as The Haberdasher Baljeet is invited to audition for the next Space Adventure film but does not know how to act so the other kids build him an immersive set. Meanwhile, Doofenshmirtz plans to zap his brother Roger with a "Deface-inator" to make his face instantly forgettable. Baljeet struggles getting into character, but the other kids stage an attack from an animatronic slug monster so they could elicit a true performance from Baljeet. The film's director Katherine Marshall reveals that Baljeet was asked to be an extra in the film instead of the lead character Exterra, but sees his performance and decides he is too good to be an extra. Doofenshmirtz's inator hits Roger's new statue, which boosts Roger's reputation when they believe Roger is showing humility. Katherine takes the set, foiling Candace's attempt to bust the boys. Guest star: Lake Bell as Katherine Marshall

Meap believes that Big Mitch has been running fake tours as a front to obtain funds in search of the "Lost Treasure of Zachariah Yore" to fund his criminal empire. When his Alliance does not believe him, he goes rogue and reunites with the Flynn-Fletcher kids and their friends for assistance. The kids create "Stabby Barf Pain", a combination of all four seasons, to lure Mitch to Earth. Candace and Meap investigate the location of the treasure, tracking it to the Gateway Arch in St. Louis, Missouri. The alien tourists start to trash the city, but the kids are able to wrangle them together through a performance. Candace and Meap get caught infiltrating Mitch's ship and "accidentally" reveal the location of the treasure. As Doofenshmirtz has Perry help him find new ways to act "maniacal", Mitch steals Balloony, so the two follow onto the ship. As Mitch pulls the Arch out of the ground, the Alliance arrives and learns Meap was telling the truth, forcing Mitch to flee; Doofenshmirtz prevents the ship from self-destructing. Mitch steals Meap's ship, but he and Candace trick Mitch into pressing the self-destruction button, and he is captured. The Alliance Commander and Meap reward Candace for her bravery, and they take the boys' Stabby Barf Pain machine.

Phineas, Ferb, and their friends have a slumber party at the same time Candace is having one with Stacy and Vanessa. Meanwhile, in a bid to one-up his neighbor who spoils all TV shows, Doofenshmirtz plans to watch the finale of the series Acquaintances and spoil it to the entire Tri-State Area with a giant megaphone. The kids hang out in an inflatable dome where the floor is made of popcorn to watch movies, while Stacy and Vanessa attempt to dissuade Candace from busting the boys. Doofenshmirtz's "Awake-inator" fails to keep him awake, and Perry destroys both of his machines. Stacy and Vanessa join the kids in their dome, so Candace forcefully drags her sleeping mother outside to see it. The inator misfires on some birds, who eat the popcorn and pop the dome, causing it to fly away. Phineas and Ferb build a "forced perspective" old west styled town in the backyard to convince Baljeet to like western movies. While Doofenshmirtz is out of town, Major Monogram and Carl get lost while on an excursion in the swamp, so Perry goes after them. Perry gets caught in a trap and taken to the shack of Doofenshmirtz's cousin, Bubba, who intends to eat Perry. Monogram and Carl discover Perry and the three manage to escape Bubba, who crashes into a beaver dam. Baljeet gains a fondness for western movies, and when Linda arrives, the town is revealed to be just a tiny model, which Candace confusingly points out is not how "forced perspective" works.

The Candace Suit brought to life by Doofenshmirtz's leftover-revive-inator attempts to eat Jeremy, who runs for shelter at the Flynn-Fletchers' house. The Candace Suit eats Doofenshmirtz and tries to pass herself off as the real Candace before she slips on a banana peel and spits him out. The kids give chase to the Candace Suit, which fights the real Candace, swallows her, and successfully passes herself off as real for a day until Jeremy becomes suspicious and has Phineas and Ferb use their banana peeler to free the real Candace. Buford translates the Candace Suit's garbled speech that she had been feeling lonely ever since being brought to life. To make sure the Candace Suit is with somebody while also keeping humanity safe, the kids bring her to the Himalayas to live with Klimpaloon. Linda suspects that Samantha Sweetwater - a friend from her book club and mother of Fireside Girl Adyson - does not actually read the books. Linda and Candace discover that the club's latest book has been made into a movie and decide to bust Samantha. They infiltrate the Sweetwaters' backyard while Samantha is driving Adyson, recruiting their neighbor Irving. They see that the book has barely been touched but are unable to get closer when the Sweetwaters return early, so they go to the movie theater to catch Samantha. However, they discover that the entire book club could not finish the book and is at the theater to watch together. Samantha admits to Irving that she never reads the books. In the background, Linda constantly sees a giant tube man without realizing her sons built it, and Perry stops Doofenshmirtz from covering the entire Tri-State Area in guacamole. Guest star: Anna Faris as Samantha Sweetwater

"Mantis Fact!"

James Kim

Deena Beck & King Pecora

Doofenshmirtz takes Vanessa to Drusselstein to take her citizenship test, which he also decides to take since he was never able to finish his as a teenager. When they arrive, Doofenshmirtz is surprised to see how modernized the town has become, and how significantly easier and less humiliating the citizenship test is, disappointing him as he believes seeing the depressive state of the town he grew up in would give Vanessa her own "tragic backstory". He retools his original Inator into one that begins reverting the town back to its more primitive self, until Perry stops him. He ultimately decides to do what his parents never did for him and be there for Vanessa, and the two receive their citizenships. Meanwhile, Linda loses her wedding ring in the sink pipes, which fall deep below the house, so Phineas and the gang build a massive drill to head underground looking for it. Candace falls into the hole (briefly passing through Perry's lair unknowingly), is chased by mole people wanting her to be their Queen, and reunites with the kids. They find the ring and are blasted out of the underground by a flood of water thanks to Doof's inator. Phineas and the gang create a giant birdhouse on top of their tree in order to attract the Mockmacaw, a bird with the capability to shapeshift into anything and anyone, hoping to get a picture of it. Meanwhile, Perry discovers Doofenshmirtz's lab has been taken over by giant mantises; thanks to a book on Mantis Facts given to him by Vanessa, Doofenshmirtz was inspired to use an Inator to make them bigger to deal with other bugs, only to make them too big. Doofenshmirtz is suddenly proposed to by one of the mantises, which he accepts and orders them to capture Perry. Perry soon informs Doofenshmirtz that mantis women eat their husbands, which they plan to do to him, forcing them to flee again. At the same time, Phineas and the gang manage to attract the Mockmacaws, but are unable to get a picture of their bird forms. In the city, Perry gives Doofenshmirtz a battery to power his Inator, allowing him to shrink the mantises back to bug size. However, one of the rogue blasts hits him, shrinking him to their size. Candace eventually notices the birdhouse and tries to get Linda to see it, only for it to shrink thanks to another rogue blast. Doofenshmirtz tries to grow himself back with the Inator, but accidentally shrinks himself even smaller than the mantises, and is surrounded by them. Later, Candace starts to freak out seeing Linda and the kids as Mockmacaws, and even herself starting to become one.

"Doof in Retrograde"

Chris Ybarra

Bryan L. Francis, Sang Young Ha & Deena Beck

On a peculiarly cloudy day, Candace fails to bust the boys' giant robotic scarecrows. Meanwhile, Doofenshmirtz has created an inator that projects people's dreams so he doesn't have to hear them poorly described. He hits Perry with it, revealing his dream where he becomes a giant and accidentally destroys the city. He then fires it at Vanessa, showing her fighting off an army of zombie Ducky Momo's. Perry begins battling Doofenshmirtz, causing the inator to misfire throughout the city. Buford and Baljeet are hit, revealing a dream in which Baljeet has become a brain monster intending to infect Buford and the others. Candace is hit and dreams of being a medieval warrior, trying to bust the boys while evading the "mysterious force". Ferb has a surrealist arthouse dream. Isabella dreams of a cupcake takeover that she and the Fireside Girls battle. Linda dreams of being stalked by Candace in the shower. Doofenshmirtz is finally hit and dreams of taking over the Tri-State Area. Suddenly all the creatons from the past dreams break out of the projector, which Perry fights, only for it to all still be part of Doofenshmirtz's dream; Perry destroys the inator. Phineas, Ferb, Isabella, and Buford ride floating dandelions while Baljeet observes from below. Irving appears, wanting help to create an invention to impress Phineas and Ferb, so Baljeet agrees to help him. Candace decides to go for a different approach and act "casual" to trick the "mysterious force" in her effort to bust the boys. Meanwhile, Doofenshmirtz has created and is wearing a device that makes him "the centre of his own universe", causing makeshift planets to orbit around him at an increasingly dangerous rate. After some trouble, Perry is able to press the self-destruct button on the suit, destroying the planets and saving Doofenshmirtz. Just as Phineas and the kids finish playing on the dandelions, Irving and Baljeet arrive with their flying unicycle, only for it to be blasted away by one of the planets before they can show the others. Irving is ecstatic one of his inventions has disappeared just like Phineas and Ferb's, and runs off to make more.

"Dooflicated"

Amber Tornquist Hollinger

Olivia Olson & Martin Olson

Sofia Alexander, Wendy Grieb, Deena Beck & King Pecora

A Doofenshmirtz livestream is interrupted by the presence of rival Major Monogram, who disputes the fact that O.W.C.A. only exists to thwart Doofenshmirtz's evil schemes. Viewers suggest L.O.V.E.M.U.F.F.I.N. square off in soccer against O.W.C.A., with the stipulations that if the former wins, Monogram shaves his mustache and Carl's head, and if the latter wins, Doofenshmirtz has to shave his head. Back at the Flynn-Fletchers, Buford has trouble when playing a game of "Can You Hit That Thing with a Stick", a game that even Candace finds dull, so the others try to help his aim by creating a practice arena. Doofenshmirtz's Bring-Me-A-Ringer-inator summons professional player Cristo Fernández to act as L.O.V.E.M.U.F.F.I.N.'s ringer, with Vanessa becoming the team's cheerleader. Noticing Fernández's presence during training just before the match, Monogram recruits professional player Megan Rapinoe as O.W.C.A.'s ringer (also her house was being fumigated). With Klimpaloon officiating and Dink Winkerson, who escaped from prison, narrating, the match begins and immediately devolves into insanity. The match tied, Fernández and Rapinoe leave, and Monogram joins the field himself but is shown a red card due to aggressively tackling several L.O.V.E.M.U.F.F.I.N. scientists and Doofenshmirtz himself. Due to divine intervention from Phineas and Ferb's use of jets to shift the Earth eight inches to the left, Doofenshmirtz's penalty kick misses, leaving both teams tied. Monogram and Doofenshmirtz concede defeat, with the former acknowledging the game helped him understand the importance of Doofenshmirtz and L.O.V.E.M.U.F.F.I.N to O.W.C.A.'s operation. Both Monogram and Doofenshmirtz, upholding their ends of the deal, shave their heads, but Carl escapes before he can shave his head. Guest stars: Cristo Fernández and Megan Rapinoe as themselves It is Danville Day, and Phineas and Ferb plan to spruce up the festivities by building a city-wide carnival ride. With their parents attending Roger's speech, Candace is naturally left in charge. At Doofenshmirtz's, he realizes Vanessa's college essay has named his brother-turned-city-Mayor Roger as her "most positive role model", which upsets Doofenshmirtz to the point of creating the Dooflicate-inator, which gives its target his personality and his Drusselsteinian accent. The beam instead hits Phineas, Ferb, and the other kids, turning them evil in front of Candace's eyes. The kids repurpose the rides into Fun-inators to take over the Tri-State Area. While Perry fights Doofenshmirtz in an attempt to wrestle control of the Dooflicate-inator away from him, Vanessa tells Candace every inator has a self-destruct button, which when pressed will revert everyone back to normal. Candace is able to find the self-destruct button, but is trapped in a giant hamster ball that is soon launched into the Fun-inator's self-destruct button, which turns everything evil into an explosion of glitter and confetti. Reuniting with her father, Vanessa tells him she only mentioned Roger to boost her college chances, revealing that it was not out of genuine respect for him, which makes Doofenshmirtz proud. Perry then destroys the Dooflicate-inator, turning everyone back to normal.

"Droogenfest"

James Kim

HyeonJeong Chozon, Nadine Promes García, Ram Patel & King Pecora

Against a sick Buford's wishes, Baljeet shows him an episode of his favorite show, Space Adventure, titled "Gauntlet of Death". The crew of the U.S.S. Minotaur - captain Dirk Mortensen, lieutenant Zarna, cadet Sophia Sharkboard, pilot Nosh, security guard Lomond, and robot DSL-4 - steal the secret plans for the Spiky Ring, a new superweapon being constructed by the Honey Badger Empire and find out their next target is Earth. Dirk alerts the Honey Badger fleet and provokes their commander, Rrrrg, prompting a chase through the cosmos that ends on them crash-landing on the Moon, and the pursuers all combining into a large spike that crashes into the Pacific Ocean, ending the episode on a cliffhanger. As Baljeet prepares to show Buford the next episode, text reveals that Buford never actually liked Space Adventure, feigning interest only so he can infect Baljeet with his cold. The annual Tri-State Area Droogenfest, which revolves around the signature dish of droogen strudel, is being held, and Fireside Girls Troop 46321 is tasked with creating an authentic droogen strudel to appease Drusselsteinian emissaries, who are planning to strike a trade deal with the Tri-State Area should the dish be perfect. Phineas and Ferb have created the largest doonkelberry for showcase at the festival; Perry is told to investigate Doofenshmirtz's presence. Doofenshmirtz's failed attempt to join Isabella and the Fireside Girls ends up reuniting him with her after their shared space adventure. Perry arrives, and Doofenshmirtz reveals he has a hatred of droogens and wants to swap them out with the Droogen-Chocolate-Swap-inator. While the inator is destroyed, it successfully swaps all the droogens with chocolate, causing the emissaries to cancel their trade deal and threaten to downgrade the Tri-State Area to a Bi-State Area. Doofenshmirtz works together with Isabella and the Fireside Girls to bake another strudel, while Perry distracts the emissaries before they are able to leave so they can taste the new strudel. Satisfied with the strudel, the emissaries go through with the trade deal; Isabella gives her troop and Doofenshmirtz patches (the latter after he revealed he was the creator of the inator). Doofenshmirtz reveals that Isabella looks very similar to his dentist, a male dentist who has a striking resemblance to Isabella.

Chris Ybarra

Dodo Kitcharoen & Derek Lee Thompson

Doofenshmirtz has created a powerful inator, the End-All-Be-All-inator, which turns out to be so powerful, the entire building goes out. Seeing a man powering a treadmill solely by running gives him an idea: using kinetic energy generated by humans to power his inator. An infomercial Doofenshmirtz has made promises free workouts, and inadvertently discloses his true intentions; Perry goes to the new gym, titled the Doofnasium, to investigate. Meanwhile, Phineas and Ferb have created a land boat that works by temporarily altering the molecules of asphalt on the road, changing them to liquid, to allow movement; they pass Candace, who is on a date with Jeremy. Seeing the boys, Candace takes her boat (and Jeremy) on land, intending to catch - and bust - her brothers. Good timing, too; her mom is having her hair done, and the boys will cross by the building she is in soon. Doofenshmirtz's inator is overloaded by Perry as he defeats his nemesis, which ends up causing a power surge across town. Linda's hair becomes frizzled, which means she does not see the boat; it ends up sinking underground, just as the farmer and his wife argue about transportation around an underwater lake. Phineas and Ferb showcase Croquet Y-8, a giant-sized intermediary between Football X-7 and Hockey Z-9 that uses quantum portals to hit goals placed around the world. Meanwhile, Candace, wanting to take up multitasking, is working with Jeremy on a video about Perry for college credit. This leaves Perry at an impasse: he is needed to do the video, but he has to come to his briefing with Monogram. Perry deploys a robotic Perry decoy, and goes down to his lair, where he is told he has to defeat Doofenshmirtz, who has been taking up animal husbandry, in less than three hours. Doofenshmirtz, who has been wrangling sheep, has created the Go-to-Sheep-inator to help everyone in Danville go to sleep in order to take over the Tri-State Area. With time on the line, Perry immediately attacks Doofenshmirtz, and is able to use a ball of sheep he created against him, defeating him with 30 seconds to spare. Meanwhile, under Jeremy's supervision, the Perry-bot begins to malfunction and go haywire, while Candace is outside watching the Croquet Y-8 game. Candace gives up on multitasking as the ball of sheep Perry created takes away the croquet stuff, leaving the backyard with the usual sights of nothingness, but the tree. The Perry-bot finally explodes as the real Perry returns, with Jeremy having obtained good footage overall. The giant sheep ball ends up at the farmer and his wife's sheep farm.

Buford asks Phineas and Ferb for help with a big ball of Christmas lights that ended up being so heavy, it collapsed the Van Stomms' garage. The two use a pair of drones they used earlier for chores to put on a light show. Meanwhile, Vanessa and boyfriend Monty arrange a dinner date with their fathers and their sidekicks, Norm and Carl, respectively. Doofenshmirtz, who has completely ignored Vanessa's pleas for good behavior, has secretly installed the Tableturn-inator, a device that spins a table his way, allowing him to get the best food. Monogram soon finds out Doofenshmirtz and Norm are both present; soon, childish arguments begin for control over the red chair, where Doofenshmirtz has installed the switch, which devolves further into food fights. Soon, Perry, who was invited by Monogram, arrives and admonishes his rival and superior for their behavior. However, this leads to yet another argument as the inator shorts out, making it spin and lift into the air. Phineas and Ferb's drone show is well-received by the gang; shortly after the kids leave, Candace, seeing an open goal, attempts to use the drones to bust the boys, but the flying restaurant crashes right into the drones as she brings her mom out for yet another failed bust. Perry is able to disable the inator, restoring stability to the restaurant; Doofenshmirtz and Monogram reconcile, and reaffirm their rivalry - agreeing not to interfere in their kids' relationship. Speaking of their kids, they admit they genuinely like each other amidst the chaos; and the bill Doofenshmirtz is given includes damages to the restaurant, which he attempts to trick Monogram into paying for. Phineas and Ferb unveil the Bread Bowl Hot Tub, an invention long-desired by Buford ever since the summer began. Finally getting his big break, Buford spends time in the hot tub, only to find himself stuck in a remote island; such is the result of Doofenshmirtz's new inator, the Carb-Away-inator, which pushes away food with a high amount of carbohydrates (i.e. bread). When Perry attempts to thwart him as usual, he tells his rival he has made the inator so he can improve his health. Now stranded and with no way to find food, Buford's isolation makes him hallucinate the voice of the hot tub, which he named "Chowdina"; the hot tub tells him to commune with nature, but his pacifism does not last long as he immediately finds Chowdina being attacked by rogue seagulls. Witnessing this happen, Buford builds a raft and, with Chowdina, braves the rough conditions; he soon finds himself floating back to Danville due to the Carb-Away-inator's effects being reversed, bringing all bread, including Chowdina, back to Danville (Buford believes it is the "power of friendship" bringing them home). Doofenshmirtz's attempt to improve his health is thwarted by his cravings for bread, so he asks Perry to destroy the inator. Doing so makes all the bread fall to Earth, where Chowdina crashes into the ocean and disintegrates, much to Buford's sadness; he soon accepts her fate, telling the others that Chowdina will forever live on in his heart.

With Doofenshmirtz away, Major Monogram has decided to conduct a routine test of Perry's lair entrances with Carl as his lab rat. Meanwhile, the gang decides to conduct a (non-bustable) activity of trying to find the perfect mix for an Arnold Palmer. Phineas has Isabella score the drinks, Baljeet on chemistry balance, and Buford on quenchability. While Carl tests the entrances, he ends up getting stuck on one of the entrance tunnels. Candace gets wind of a giant juice maker the kids have made, but ruminates on whether to bust them or not, as the "Mysterious Force" would end up taking it all away by the end of the day anyway. Suddenly, she hears the Mysterious Force (a.k.a. Monogram talking to Carl), who tells her to wiggle. After she asks the Mysterious Force to give her a sign, it immediately complies and indeed, shows her one, so she calls Stacy over to show her the situation. While the kids continue to test Arnold Palmers, Candace shows Stacy around the house to prove that the Mysterious Force is real and is able to convince her; Candace calls her mom to get home within ten minutes. Meanwhile, Monogram has been attempting to help Carl get out of the tunnel as he receives an alert that Perry's host family are on their way home, while Doofenshmirtz's patience with a pool boy finally runs out as he makes an impromptu inator - the Bring-Me-a-Drink-inator. The kids' testing devolves into arguments, solved by a mint leaf that makes the Arnold Palmer perfect. After Carl points out one of the entrances that may be able to free him, Monogram engages many entrances, while Candace brings her mom ...to the kids' Arnold Palmer stand. Candace brings them to the back, but the juice maker has disappeared, as Monogram this time makes the invention disappear... landing right on top of Doofenshmirtz, who is quenched. Perry disables the last entrance just in time as yet another Candace busting attempt fails spectacularly; Carl has finally completed the routine test, but has only scratched the surface as he now needs to test all the international entrances, too. A shocked Buford and Baljeet informs Phineas and Ferb that their favorite TV series, Stumbleberry Finklebat, has been cancelled due to unresolved contract negotiations. They decide to build a dungeon-crawling experience inside a dodecahedron die, one that Candace reluctantly joins as she dislikes LARP. The gang, joined by many others, enter the dodecahedron and explore the dungeon to write their own conclusion, but Buford falls into a trapdoor, so the gang go forth to rescue him. Encountering a booby-trap filled section of the dungeon, Candace nonchalantly walks past all the traps and saves Buford. Meanwhile, Doofenshmirtz is on the lookout for love on a dating app; against his daughter's advice, he joins the cast of a reality dating show titled Passion Villa, where he is joined by the other contestants, Thad, Theo, and Evan. Vanessa cringes at her father's debut in the show, while Norm is fascinated and inspired to go on a date. Soon, Doofenshmirtz decides to shake things up with his new inator, the Shake-It-Up-inator, which eliminates the other contestants. Monogram, shocked by this turn of events, has Perry join the fray, where he immediately attacks Doofenshmirtz. Back at the dungeon, the gang finds the last shard of Darkling Dungeon, but encounters the Enigmata Obscura: the Puzzle Knight and his minions; and again does Candace find the solution: magnetizing the wall. His minions temporarily picked to the side, she is eventually cornered by the Enigmata Obscura, but the Man in Really Dark Grey (Jeremy) saves Candace and defeats him. Their conclusion to Stumbleberry Finklebat written, the gang exits the dodecahedron as Doofenshmirtz not only eliminates himself, but also makes the dodecahedron shake away just as Candace brings Linda to the back. At a restaurant, Norm meets "Robotina", only to end up "humanfished" as "Robotina" is actually a human LARPing as a robot.
