Inflatable Alien Costume
Look like you are being carried away by a green extraterrestrial.
The inflatable alien costume is a viral sensation that creates the hilarious optical illusion of a green extraterrestrial carrying you on its back. It is a massive hit for Halloween, parties, and festivals due to its lightweight design and instant comedic effect. The look consists of a self-inflating green alien body with faux human legs dangling in front to complete the abduction illusion.

How to put it together
- 1
Put on your everyday t-shirt and comfortable socks.
- 2
Insert 4 AA batteries into the fan's battery pack and clip the pack to your waistband or pocket.
- 3
Step into the legs of the inflatable suit, pulling it up to your waist like trousers.
- 4
Tighten the drawstring or elastic band at the waist and ankles to create an airtight seal.
- 5
Turn on the battery pack switch to start the fan, allowing the suit to fully inflate around you in about 60 seconds.
- 6
Adjust the faux blue legs hanging in front so they look like your own legs being lifted off the ground.
Makeup & hair
No special makeup or hair styling is required since the focus is entirely on the hilarious inflatable suit, but messy 'panicked' hair fits the abduction theme perfectly.

Tips
- Bring extra AA batteries in your pocket, as the fan must run continuously to keep the suit inflated.
- Wear lightweight clothing underneath, as the polyester material can get warm inside despite the fan's airflow.
- Make sure the elastic seals at your waist and ankles are snug to prevent air from escaping.
- Practice walking through doorways sideways, as the inflated alien head adds extra height and depth.
Inflatable Alien costume FAQ
- How does the inflatable alien costume stay inflated?
- It uses a small, battery-operated fan that clips into the suit and runs continuously to pull in outside air and maintain pressure.
- How long do the batteries last in the fan?
- A fresh set of four AA batteries typically powers the fan for about 4 hours of continuous use.
- Can you sit down while wearing the inflatable alien costume?
- Yes, but you must sit carefully to avoid blocking the fan intake, and the suit will temporarily compress and re-inflate when you stand up.
Did you know? The 'pick-me-up' style of inflatable costumes relies on a clever optical illusion where your actual legs are hidden inside the green alien legs, while the dangling blue legs are stuffed with air.
