Role in the series
In "Boating Buddies," SpongeBob, Squidward, and Mrs. Puff race through the shop in a car and receive the following costumes:
- SpongeBob SquarePants: A gorilla costume.
- Squidward Tentacles: A cooking shirt, a cooking hat, a mustache, and a rolling pin.
- Mrs. Puff: A mask and an ax.
- SpongeBob's gorilla costume resembles the Gorilla that attacked him, Sandy, and Patrick in the Season 3 episode "I Had an Accident."
- Patrick also had a gorilla costume in the same episode. This may be the place he got his from.
- Just like this location, the Bikini Bottom Prestigious Music College has a small sign on the building that read, "Parking In Rear."
- There is a different costume supply store in "You Don't Know Sponge."
- Mrs. Puff's costume highly resembles Jason Voorhees from the horror Friday the 13th series.
