Role in episode

When SpongeBob wins a demolition derby, Mrs. Puff gets mad and goes to demolition derby with a giant monster truck. She introduces herself and says "I'm the Huff." Mrs. Puff immediately drives her giant monster boat right into a crowd of fish and SpongeBob's demolition boatmobile. Some of the crowd of fish fall onto the front of Mrs. Puff's view and she uses the wipers to get them off.

After that, Mrs. Puff chases after SpongeBob, who is still driving in his small demolition boat car. SpongeBob then drives into Mrs. Puff's Boating School and crashes both him and Mrs. Puff into the classroom, destroying the giant monster truck in the process.
