Beautopia (episode)

Synopsis
Susan Strong returns and asks Finn and Jake to help fight off the Lub Glubs and regain her people's home in Beautopia.

Plot
Finn and Jake are inside one night, discussing things about coffee, when they hear banging. All of the sudden, Susan Strong bursts through the wall from the outside. She says that she needs Finn's help because of his "Hero Heart." She also adds that she needs Finn's magic, the "Red Flower," or Fire.

Jake tries to convince Finn that Susan's completely crazy, Despite this, Finn still wants to help and tells Jake that he will whether he is coming with him or not. Jake remarks that he's only coming to be "disruptive and obnoxious."

The duo are taken to the underground cave in which the Hyooman tribe lives. Susan thinks they should swim, and dips Finn's head in the water. Jake stops Susan shortly, saving Finn from drowning. Finn takes off his hat while catching his breath, Susan sees that Finn has no gills. She then decides they take a boat ride down the river and Jake sings "I'm On a Boat." A pool toy passes them, and Susan panics, telling both Finn and Jake to keep quiet, because it was a Lub Glub. They attempt to cross the Clashing Gates and pass, but the boat is broken. Eventually, they reach the city and several Lub Glubs come out. Jake is convinced that they are just normal pool toys and hits one with his Pick-Axe Hand. The Lub Glubs all turn into their true form and attack the group, to Susan's terror. Susan helps Finn fight and Jake goes to put the fire in the City Heart. When he does, all of the Lub Glubs die, leaving only their pool toy shells.

It cuts to all of the Hyoomans moving back to the city. Susan tells Finn he should stay, but Finn claims he's not like her. Susan takes his hand and puts it under her hat onto her neck. Finn is surprised by what he felt and says "Susan...." but is interrupted by Jake, who bought a bunch of soft pretzels. As they leave, Finn waves goodbye to Susan.
