"Spongicus" is an episode from Season 6.
With the idea to lure the Krusty Krab's customers, Plankton demolishes the Chum Bucket into a coliseum in it's place. He is holding a gladiator show, and Mr. Krabs, Squidward, and SpongeBob watch. But after SpongeBob sees the risk of Patrick being against a sea lion, SpongeBob steps in to save him. After SpongeBob throws the smoke sausage ring on Plankton, the sea lion is risking to chase after him, having the Krusty Krab's customers back, but Mr. Krabs turns a Krabby Patty's amount into $10.00. A customer doesn't agree with this, but soon changes his mind after looking at the financial expert (the sea lion). Mr. Krabs, Squidward, SpongeBob, and Patrick all laugh, but then left after they get tired of laughing. The camera zooms to the exterior of the Krusty Krab, and the sea lion roars one more time before the episode closes.
