A new fad, Animology, has taken Middleton High by storm and everyone is into it, except Kim, who doesn't understand the appeal (describing it as "a lame cross between astrology and a personality quiz"). After Ron is deemed a "pink sloth" by the fad, he declares it bogus and leaves his book behind, which Kim finds. Despite her previous dislike of it, Kim soon finds herself working through the night on the Animology test and learns that she's a "blue fox."

Meanwhile, Senior Senor Sr. and his son chill at the Billionaires Club after Kim foiled an earlier scheme of theirs, but the club's president, Philippe Bullion, suspends Senior's membership, due to his losses to Kim poorly reflecting on them. Vowing revenge, Senior steals a "cryovator" device from frozen food magnate Pop Pop Porter, which Kim is called on to investigate. Tracking the Seniors to their island, she and Ron are captured and strapped to a conveyor belt leading to the cryovator, while Senior plans to use a larger version to freeze the Billionaires Club. Kim also learns that Junior is into Animology and that he is a "yellow trout" which is supposed to be the blue fox's soul mate, much to her disgust.

With Rufus' help, the heroes manage to escape and arrive at the island that serves as the Billionaires Club headquarters, rescuing Bullion in the process. Senior attempts to destroy the duo with missiles, when Junior recalls Ron earlier calling Kim a "blue fox" and keeps his father from hitting them, the missiles destroying the jumbo cryovator instead. As Junior declares his love for Kim, an angry Senior flies them back to the island to plot revenge. Back at Middleton High, Kim receives a large amount of flowers and a video from Junior. Ron again expresses his dislike for being a pink sloth, causing Amelia to be relived, since that's supposed to be her soul mate. As Ron chases after her to make his case, Kim puts one of Junior's flowers into her hair.

----
!! This episode contains examples of:

* AbhorrentAdmirer: Junior for Kim.
* AbortedArc: Junior being in love with Kim basically started and ended with this episode.
* BalloonBelly: Ron and Rufus both get one after eating a whole mess of Pop Pop Porter's corndogs.
* BigRedButton: Senior's conveyor belt has one, and Rufus manages to push it (after getting fat enough) to save the day.
* BlatantLies: No, Kim's not into Animology, she's only doing it for laughs.
* BondVillainStupidity: [[LampshadeHanging Pointed out]] by Senior himself.
--> '''Junior:''' Did we not leave Kim Possible on [[ConveyorBeltODoom a conveyor belt to her doom?]]
--> '''Senior:''' Yes, a proper villain always leaves his foe when he's about to expire.
--> '''Junior:''' Why?
--> '''Senior:''' Well, it would be bad form to just lull about, waiting for it.
--> '''Junior::''' Why?
--> '''Senior:''' Tradition.
* CallBack: Kim and Ron's "crimes"/"corn dogs" argument is similar to their "TakeOverTheWorld"/"steal Christmas" one they had back in [[Recap/KimPossibleS1E1Crush Crush]]; it even has the villain admitting that Kim was right and her being smug about it.
* ComicallyMissingThePoint:
--> '''Ron:''' Tell me you don't wanna know your perfect mate.
--> '''Kim:''' Not if he's some...blue baboon.
--> '''Ron:''' Don't even joke Kim, a blue baboon would be disastrous for you.
* ContinuityNod: Amelia appears, [[Recap/KimPossibleS1E3TheNewRon yet]] [[Recap/KimPossibleS1E15AllTheNews again]].
** Also, Kim helps Pop Pop Porter, as she [[Recap/KimPossibleS1E15AllTheNews did once before]].
* ConveyorBeltODoom: Senior leaves Kim & Ron on one, leading to the cryovator.
* DatingCatwoman: [[DiscussedTrope Discussed by Senior]] "Junior, dating an arch-foe is spitting upon villain tradition."
* DisproportionateRetribution: Senior seeks to freeze the entire Billionaires Club just because they kicked him out. [[LampshadeHanging Lampshaded]], naturally.
--> '''Senior:''' World class villains are defined by disproportionate revenge.
* DumbassHasAPoint: Ron was right when he pointed out that Animology was bogus--while the test itself may accurately predict a person's personality traits (for people in Middleton at least), it's not accurate when it comes to predicting someone's "perfect soulmate" (with the possible acception of Kim's parents, who both took the test and were excited to see that they were soulmates).
** Case in point: Animology claims that the "perfect soulmate" to a blue fox (Kim) is a yellow trout (SSJ), but she ultimately ends up with the pink sloth (Ron).
* HarmlessFreezing: What the cryovator causes luckily, or Ron would've lost his feet and Bullion his hand.
* {{Hypocrite}}: Kim claims that she avoids fried foods, but, as one commenter at the defunct TV Tome put it, she regularly eats at Bueno Nacho and "they're not called "rebaked" beans."
* ITakeOffenseToThatLastOne: Animology describes the pink sloth as "[[ArsonMurderAndJaywalking an outcast, a follower, socially inept and smells of overripe fruit]]."
--> '''Ron:''' I do not smell of overripe fruit! ''(Rufus pops out of his pocket with an old banana peel)''
* LikeAWeasel: Ron is more than willing to go along with Animology like everyone else, until it dubs him a "pink sloth," after which he quickly decries it.
* LiteralMinded: After Senior suggests freezing the club members assets as a way to get even, Junior comments that such a task would require a large freezer.
--> '''Senior:''' I was not speaking literally my son!
* OutOfOrder: This episode was produced before [[Recap/KimPossibleS1E15AllTheNews All The News]] but aired after, hence why Kim doesn't recognize Pop Pop Porter despite helping him in the latter episode.
* SeriousBusiness: Animology is this to the students at Middleton High, even going so far as to not sit with people who seemingly conflict with their profile.
* StatusQuoIsGod: The whole "Junior wanting Kim to be his soul mate" thing was dropped after this and never brought up again.
* WhyDontYouJustShootHim: Junior wonders this when Senior plans to blast some icicles on the heroes.
--> '''Junior:''' Why did you not just aim the laser at their bodies?
--> '''Senior:''' Junior, if you do not understand the traditions of villainy, I have failed as a father.
