How to put it together
- 1
Insert four fresh AA batteries into the battery pack and connect the fan cable.
- 2
Step into the legs of the unicorn suit, pulling the elastic waistband or straps up to your waist.
- 3
Clip the battery pack securely to your own pants pocket or belt; do not put it in the costume pocket to avoid blocking the fan.
- 4
Turn on the fan switch to begin inflating the suit, ensuring the elastic bands at the ankles and waist are snug to trap the air.
- 5
Once fully inflated, put on the matching pointy hat and adjust the faux rider legs so they drape realistically over the sides.
- 6
Double-check that the air intake valve on the outside of the suit is completely unobstructed.
Makeup & hair
Keep makeup simple and bright with colorful face glitter or pastel eyeshadow. Style your hair in a high ponytail or braids so it fits comfortably under the cone hat.

Inflatable Unicorn costume FAQ
- How does the inflatable unicorn costume stay inflated?
- It stays inflated using a small, built-in electric fan powered by a battery pack. The fan constantly blows air into the suit, while elastic bands at the openings keep the air from escaping.
- Can you sit down while wearing an inflatable unicorn costume?
- Yes, you can sit down, but the costume will temporarily deflate slightly as air is pushed out. It will quickly reinflate once you stand back up.
- What should I wear underneath the blow-up suit?
- Wear light, comfortable clothing like a t-shirt and leggings or shorts. Avoid bulky clothes, which can restrict airflow and make you overheat.
