When they arrive, SpongeBob covered almost everything in the museum, much to Mrs. Puff's dismay. SpongeBob went to the control room when they were ready to leave and accidentally started the boat (someone was actually steering it and not SpongeBob). SpongeBob thought he drove it himself because he stayed up all night the previous night and he could impress the teacher. Although, at the end, the person who was actually driving the boat gave him his honorary Sea Legs and offered to buy ice cream for him. SpongeBob then noticed the headlights were on when they were leaving. He then accidentally flipped the museum over when he tried to turn them off.
