Role in episode
Larry tells SpongeBob and Squidward to give the customers their protein power shakes. SpongeBob gives one to Peterson Nat Tucker, who is on the rock climbing wall. The protein power shake drops on his head and he falls off the wall. Squidward tries to give one to a customer but he trips on the hurtles. Bubble Bass eventually tastes the shake and calls it a horrible substance.
After Squidward's escape plan fails, he gives SpongeBob a plan to sabotage Larry's training sessions. SpongeBob does his plan but forgets to untangle Squidward. His plan is to put butter, lard, and mayonnaise in the protein power shakes. He gives them to Larry and his friends. However, instead of drinking them, Larry puts it on his chest.
