Finn and Jake attempt to track down President Porpoise before Vice President Blowfish takes over.
- Black Comedy: At the end of the episode, Finn and Jake sit around in the submarine for Banana Man to come and take them back to the surface, not knowing he has already left. They comment on their dwindling oxygen supply, but don't seem particularly troubled by their imminent suffocation.
- Continuity Nod:
- Jake mentions that he and President Porpoise video-chat sometimes, a nod to Porpoise's first appearance in "Burning Low".
- BMO is shown having an intense role-playing session again.
- Marceline is hiding in the treehouse again.
- Evil Chancellor: Vice President Blowfish is depicted as this, demanding that he be made president. Finn and Jake think Blowfish is behind President Porpoise's disappearance, and Jake attacks him to try and get a confession from him, but in the end he turns out to be innocent.
- Overly Long Gag: After Ice King and Banana Man suddenly reveal they've been hiding in Finn and Jake's house, Finn asks out loud if anyone else wants to come with them, and hearing no reply, leave. Then Marceline, Princess Bubblegum, Starchy, Crunchy and Gumdrop Lass 1 come out of hiding.
- "Shaggy Dog" Story: President Porpoise was never missing. He was just on vacation and the octopus forgot about it.
