This balloon is especially fun because it floats as if it’s walking around the party room. 52". Pattern is printed on both sides of balloon. May have two different images on either side. Helium is what gives this balloon the ability to “walk”. Be sure to pick up a helium tank (sold separately) to bring your Airwalker friend to life! Please Note: Balloon is a 2-piece set (the body and the head). An adhesive piece is located on the neck so that the balloon can be attached to achieve the look as shown.
