Annoyed by SpongeBob’s whistling, Squidward closes the gap in his teeth. SpongeBob then becomes “cool”, with a great singing voice, and Squidward pretends to be his friend to get into a jazz club.

Squidward’s complaints trigger a volcanic eruption./SpongeBob and Patrick search for a drain on the ocean floor.

Mr. Krabs wants to save five cents, so he has SpongeBob fired from his job. SpongeBob falls into a depression, and despite encouragement from Patrick, finds that he does not enjoy being unemployed. He takes his talents to multiple other restaurants, making Krabby Patty-style food that turns out to be delicious.

Plankton creates a sauce that lowers the intelligence of whoever eats it. The fumes are sucked into an air vent, absorbed by a cloud, and rain on Bikini Bottom, turning everyone as stupid as Patrick. Sandy and Karen are the only ones not affected, and must re-educate the town.
