100cm Standing Airz Shape Ankylosaurus Foil Balloon #30211204 – Each (Pkgd.) Air-filled ONLY These foil balloons have a “body” and “legs / wheels”. Once the pieces are pressed together, the foil can then be inflated by the self sealing valve by the paper straw included in the packet (or a balloon pump). Once inflated, adjust the legs/wheels and the foil balloon will stand on its own! If the leg / wheel pops off during play, the balloon will deflate, but it is easily re-attached and re-inflated!
