Be a super sumo ninja in this hilarious and unique costume. The Inflatable Black Jumpsuit for Adults covers you, head to toe, in featureless black. There's a jumpsuit with fan, gloves and socks, and a hood. Put four AA batteries, not included, into the fan, turn it on, and watch the suit inflate. You'll look like you're going to float away. Pair it with a black skin suit to really be anonymous. You'll just be a giant black mass that resembles a huge person. Wear it as part of a cheer squad to root for your team, or as a fan on the sidelines to show your support. It's fun for entertaining, too, especially if you're part of a troop who are all wearing these suits in different colors. Of course, there's no reason you can't just wear the Inflatable Black Jumpsuit as a costume to a Halloween party. You're sure to be the most unusual looking person there.
