How to put it together
- 1
Insert four fresh AA batteries into the costume's included fan battery pack.
- 2
Step into the legs of the dinosaur suit, pulling it up to your waist like a pair of pants.
- 3
Tighten the drawstring or elastic waistband securely around your waist to prevent air from escaping.
- 4
Clip the battery pack to your own pants pocket or waistband, then switch the fan to the 'on' position.
- 5
Allow the costume to fully inflate, which should take about one to two minutes.
- 6
Put on your neutral t-shirt and top off the look with the safari explorer hat.
Makeup & hair
Keep your hair simple and tucked under the safari hat. No heavy makeup is needed, but a few smudges of brown face paint on the cheeks can add a rugged, outdoor explorer touch.

Tips
- Always carry a spare set of AA batteries in your pocket in case the fan runs out of power mid-event.
- Wear lightweight shorts or leggings underneath, as the polyester material can trap body heat.
- Ensure the elastic bands around your ankles and waist are snug to maintain maximum inflation.
- Be mindful of your surroundings, as the dinosaur's tail extends behind you and can knock things over.

- How does the inflatable dino rider costume stay inflated?
- It features a small, built-in electric fan that runs on AA batteries, continuously blowing air inside to keep the dinosaur body upright.
- Can you sit down while wearing this costume?
- Yes, but you will need to sit back carefully and let the air compress, or temporarily turn off the fan to deflate it slightly.
