Back in Bikini Bottom, Plankton steals the Krabby Patty formula and uses it to sell Krabby Patties at his restaurant, the Chum Bucket, claiming Mr. Krabs bequeathed the recipe to him. He also sends a hitman named Dennis to pursue SpongeBob and Patrick. Squidward, meanwhile, uncovers the truth about Plankton stealing Neptune's crown and goes to the Chum Bucket. Before Squidward can leave and alert Neptune, Plankton presses a button on Karen, who then activates mind-controlling souvenir buckets to control the residents of Bikini Bottom, eventually renaming the city "Planktopolis". Meanwhile, SpongeBob and Patrick come across a hazardous trench, and Neptune's daughter Mindy appears to give them encouragement by falsely claiming she magically turned them into men, and they successfully pass the trench.
