- Fish in Jellyfish Trauma Center
SpongeBob explains that the Bikini Bottom Jellyfish Trauma Center is where fish go to get treated for their jellyfish stings. As SpongeBob walks through the building, he accidentally steps on Plankton, thinking he is a pickle. SpongeBob picks up Plankton and now notices him, wondering what he is doing in there. Plankton says he is at a trauma center and SpongeBob offers him flowers.
Plankton says that he is allergic to the flowers and turns pink. Patrick, in a nurse's outfit, appears when SpongeBob says "Nurse, this hot dog needs help!" Patrick then puts a gas mask on Plankton. SpongeBob asks why Patrick is there and Patrick says that he is doing community service and that it is a long story.
Plankton suddenly inflates like a balloon and flies out of the Trauma Center. He is glad to be away from SpongeBob and Patrick, but he soon bumps into a swarm of jellyfish and gets stung.
Back in the Trauma Center, SpongeBob replies with a "Thank you for watching" as the short comes to an end.
