Head to the party wearing the Adult Deluxe SpongeBob Costume and everybody will instantly start singing the SpongeBob SquarePants theme song from the moment you arrive. Ohhhhhh, who lives in a pineapple under the sea? You of course, when you're wearing this great oceanic get-up! Featuring a yellow SpongeBob tunic with a black pair of shoe covers, you'll be hanging out with Patrick and annoying Squidward in no time when you're wearing this fun look this year.
