The SpongeBob Gavel is an object that is only seen in the episode "The Krusty Sponge."
The SpongeBob Gavel is a gavel that resembles SpongeBob. It features SpongeBob's smiling face, his arms, and his Krusty Krab Employee Hat. When struck on a hard surface, it makes a SpongeBob laugh.
The SpongeBob Gavel is seen near the end of the episode under the ownership of Horace A. Whopper. Whopper asks Mr. Krabs if he has anything else to say about his case and Mr. Krabs replies "No, your honor." Whopper slams his SpongeBob Gavel which makes a laughing SpongeBob and Mr. Krabs notices this. Mr. Krabs asks Whopper if it is a SpongeBob Gavel and Whopper says he is as he is a big SpongeBob fan.
The gavel may have a speaker inside of it because SpongeBob's laughter sound can be heard when the gravel is slammed.
