It looks like a BUBBLE, plays like a BALL! Now it comes with a brand new valve for super easy inflation. The new Super Wubble bubble ball inflates up to 30 inches in just minutes and is designed to be blown up with your mouth! Just blow into the patented, self-sealing valve or you can use almost any pump you have. Made from revolutionary XpandiumTM, Super Wubble is up to four times stronger and more tear-resistant than the original Wubble. Unlike other balls, it's super soft, lightweight and engineered to be gentle. Enjoy hours of squishy, squashy, bouncy fun as you kick it, whack it, throw it, bounce it and even sit on it!
