Next, SpongeBob accidentally spills a drop of ketchup, this makes Mr. Krabs furious. He yells at SpongeBob, calling him a "Ketchup waster," which makes SpongeBob upset. Mr. Krabs apologizes and promises that he will not make any other outbursts. Squidward then drops Bubble Bass' napkin and makes Mr. Krabs even more furious. Mr. Krabs screams again, calling Squidward a "waster" and tries to beat him up. He chases Squidward with the register boat until he eventually crashes into Larry. Larry decides to calm Krabs down with a hug.
