Finn, Jake and Ice King travel to the new Ice Kingdom to confront the person responsible for the changes.
Tropes:
- Black Comedy: Ice King dropping a frozen penguin, where it lands with a distinct shattering sound.
- Comical Overreacting: Ice King freaks out when Finn puts on a sweater with his own face, apparently thinking Finn had literally grown a second head.Ice King: Oh, I get it. The top one's fake!
- Continuity Nod: Finn encounters an ice version of Carol the Cloud Woman from "The Tower".
- Evil Laugh: Betty after getting the Enchiridion. Ice King laughs along just to feel included.
- Fisher Kingdom: It seems that even spending too long in one of the elemental kingdoms can cause someone to start morphing into that element.
- Gone Horribly Right: Patience's intention was to tap into the full potential of the princess' elemental powers. It worked a little too well.
- Heroic BSoD: The normally enthusiastic and determined Patience is so demoralized by what her spell did she becomes extremely depressed and listless (though that partially seems to be related to her strong connection to ice as an element), which seems to spread to almost everyone who got iced.
- Les Collaborateurs: Caroll the cloud rats out Finn, Jake, and Ice King to Patience because she "has a good thing here" after becoming a solid ice person.
- My God, What Have I Done?: Patience St. Pim is shown feeling remorse over her actions. She never intended for any of this to happen.
- Shatterpoint Tap: As Finn falls towards the ice dome covering Ice Kingdom, he draws his sword and aims it at the top, so that the tip shatters a hole on the top for him, Jake and Ice King to fall through.
- Theme Naming: Those transformed into ice versions of themselves take on new names reflective of their gloomy state. Ex, Choose Goose is now Achoose Goose.
- What Would X Do?: Finn gets the idea for the Shatterpoint Tap move above after asking himself what Rattleballs, his old sword-fighting mentor, would do.
- With Great Power Comes Great Insanity: Patience's spell to tap into the full potential of the elemental princess's powers worked, but the very same power also consumed their minds.
