How to put it together
- 1
Put on comfortable, lightweight base layers like a t-shirt and shorts to stay cool.
- 2
Step into the legs of the purple inflatable suit or plush jumpsuit.
- 3
If using an inflatable, ensure the battery pack is connected to the fan and clipped to your waistband.
- 4
Pull the suit over your shoulders and zip it up securely to seal in the air.
- 5
Turn on the fan switch and wait about 60 seconds for the suit to fully inflate.
- 6
Slip on the purple gloves and adjust the face opening so you can see and breathe comfortably.
Makeup & hair
No hair styling is needed as your head will be covered. If your face is exposed through a face hole, apply solid purple face paint to blend in, leaving black circles around your eyes for a cartoonish look.

Tips
- Bring extra AA batteries if you are wearing an inflatable suit, as the fan will need fresh power after a few hours.
- Wear lightweight clothing underneath the suit because the polyester material traps heat quickly.
- Carry a small straw if you plan on drinking at a party, as maneuvering the face opening can be tricky.
