How does the kids' inflatable dinosaur costume stay inflated?

It stays inflated using a small, battery-operated fan that clips onto your clothing inside the suit. The fan runs continuously to pull outside air in, keeping the lightweight polyester material puffed up.

What batteries does the inflatable dinosaur costume need?

Most inflatable costumes require four AA batteries, which are typically not included with the suit. It is highly recommended to use brand-new, high-quality batteries for maximum inflation time.

Can kids sit down while wearing an inflatable dinosaur costume?

Yes, kids can sit down, but the suit will temporarily deflate slightly as air is compressed. Once they stand back up, the fan will quickly reinflate the suit to its full size.

Tips

Always carry a spare set of AA batteries in your pocket in case the fan starts to lose power during trick-or-treating.
Keep the interior clothing light, as the sealed polyester suit can get warm quickly when running around.
Ensure the elastic bands at the wrists and ankles are snug to prevent air from escaping, which causes the dinosaur to sag.
Supervise younger children on stairs or uneven ground, as the bulky suit slightly limits downward peripheral vision.
