The exterior of Costume Supplies includes pink metal walls. It also has three windows (though there may be a fourth one that cannot be seen on the left side) and glass double doors. It also has a large yellow sign at the top that says "Costume Supplies Parking in Rear" in blue on it.
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.
