At Goo Lagoon, Plankton arrives to turn the beach into the future site of the "Chum BucketMega Bucket", and demands everyone to leave the beach. However, due to his tiny size and small voice even his bulldozer is small, no one listens to him. He concludes that he needs someone big to help clear the sea creatures of the beach for him, and encounters SpongeBob. Plankton decides to trick SpongeBob into being "assertive" in order to get the things that he wants. At first this doesn't work, as SpongeBob is naturally kind and naive. Plankton decides to give up, but SpongeBob promises to prove to him his ability to be assertive. Plankton gives SpongeBob another chance, and this time is successful in teaching him how to be mean. After a series of cruel and rude actions by SpongeBob, such as stealing everyone's hot dogs and popping a volleyball, everyone leaves the beach. Plankton then reveals his true intentions to SpongeBob, making him very upset. SpongeBob defeats Plankton by becoming "aggressively nice" performing kind actions that attract the people back to the beach. Plankton leaves the beach, disgusted by the overwhelming amounts of kindness.
