History Recap / AdventureTimeS5E8MysteryDungeon

* BaitAndSwitch: Shelby seems like he's going to perform a HeroicSacrifice to kill the fish monster by serving as bait... but he instead has ''Tree Trunks'' used as bait.
* BewareTheNiceOnes: It's Tree Trunks who ultimately gets them out of the dungeon and is one of the few people to get Lemongrab to behave himself.

* ImAHumanitarian: Lemongrab has shown on several occasions to be cannibalistic, especially towards Ice King.

* TheLancer: Tree Trunks, of all characters, fulfills this role in this episode. She gets tough with Lemongrab and, surprisingly, courageous and violent in the bit with the giant fish.

* RagtagBunchOfMisfits: Ice King is a loony ice wizard prone to kidnap princesses. Tree Trunks is a miniature, yellow elephant that bakes exquisite apple pies and is in love with a pig. Shelby is a worm that spends most of his time hanging out inside a dog's viola. NEPTR is a makeshift robot made of a microwave and a can, designed to produce pies out of nothingness, and given life by one of Ice King's magical lightning. And Lemongrab is Princess Bubblegum's failed attempt at creating sentient life, is literally made of lemon matter, and has a temper as sour as his namesake. Very misfitting, indeed, especially considering Ice King forgot NEPTR was his (kind of) son.

* TheChick: Shelby doesn't really do much. He was ''supposed'' to serve as bait for the fish monster but got Tree Trunks to do it instead.

* AccidentalMisnaming:
** Tree Trunks calls NEPTR, Ice King and Lemongrab "Nectar", "Ice Cream", and "Lemoncarb".
** Ice King mistakes NEPTR for BMO.

* TheSmartGuy: Ice King intended for BMO to play this role, but accidentally grabbed NPTR instead.
