The amazing Wubble Bubble Ball is like no other ball you've ever played with before! It looks like a bubble, moves like a bubble, but you play with it like a ball! You can kick it, whack it, throw it, bounce it - and even sit on it! Made from top-secret Super-Thermo Stretch-tacular stuff, Wubble Balls are squishy, super-soft and lightweight, and they inflate to a gigantic THREE FEET TALL! The Wubble bubble ball is fun to play with indoors or outdoors, all year round. A wubble pump is recommended to properly inflate and deflate your wubble.
