How to put it together
- 1
Insert four fresh AA batteries into the fan's battery pack and screw the cover shut.
- 2
Step into the legs of the dinosaur suit and pull it up to your waist like a pair of overalls.
- 3
Clip the battery pack securely to your waistband or pocket inside the suit.
- 4
Put your arms through the sleeves and carefully pull the hood over your head, aligning your face with the clear plastic viewing window.
- 5
Turn on the battery pack switch to start the fan and begin inflating the suit.
- 6
Zip the back zipper completely closed and adjust the elastic bands at your wrists and ankles to seal the air inside.
Makeup & hair
Since your head and face are completely enclosed inside the suit, no makeup or styling is required. Tie long hair back in a low bun or ponytail to keep it away from your face and the viewing window.
