Role in episode
When Plankton finds Patrick eating a plate full of Krabby Patties outside the Krusty Krab, he comes up with an idea. He gets Patrick to believe he's his conscience and he commands him into giving him a Krabby Patty so he can figure out the secret formula. Plankton dresses up in a suit and tie and introduces himself to Patrick. He asks him to give him a Krabby Patty, but Patrick had some other things to do. They went to Goofy Goober's Ice Cream Party Boat to eat some ice cream. But Plankton blurts out that he hates ice cream. The two get into a long nose sword fight, which resulted in making a big mess. After getting kicked out, Plankton grabs the list, crosses everything out and writes a message to have Patrick bring a Krabby Patty to the Chum Bucket. Plankton nearly succeeds with his plan, but the patty flies out of Patrick's hand and lands into Pearl's picnic basket while driving to the beach with her friends. Plankton and Patrick follow them and get sucked into Pearl's mouth along with the patty. As they search for the patty, they meet up with Geppetto and Pinocchio, who thought they are thieves trying to steal food. Soon, they all get into a fight inside Pearl's stomach, giving Pearl a horrible taste of indigestion. Luckily, Karen gives her a bottle of gush and flush stomach reliever, and she spits Geppetto, Pinocchio, Patrick and Plankton out. As Plankton goes to take the Krabby Patty, Patrick's real conscience appears and tells him that Plankton is probably a bug, prompting Patrick to step on Plankton repeatedly.
