How to put it together
- 1
Put on lightweight, breathable undergarments like a t-shirt and shorts to stay cool inside the vinyl suit.
- 2
Unscrew the battery pack cover on the costume's fan, insert four fresh AA batteries, and screw the cover back on.
- 3
Step into the leg openings of the SpongeBob jumpsuit and pull the suit up over your shoulders.
- 4
Ensure the elastic bands or drawstrings at the wrists and ankles are snug against your skin to prevent air from escaping.
- 5
Turn on the battery pack switch to start the fan, then carefully zip up the back closure completely.
- 6
Stand still for about 60 seconds while the fan fully inflates the square body of the costume.
Makeup & hair
Since your face is visible through the clear viewing panel or face hole, no complex makeup or hair styling is required. You can wear a yellow beanie or style your hair flat to keep it out of the way of the viewing window.

- Watch your clearance when walking through doorways or crowded spaces, as the square shape is wider than a normal body.
