The Twirlywoos are in a room full of model aeroplanes watching a model maker starting a new project. As the man unpacks the parts of his model plane, he can't help but pop some of the bubble wrap packaging. The Twirlywoos think this looks like great fun, and they decide to pop the bubble wrap too - much to the man's surprise! Back on the Big Red Boat, the Twirlywoo Screen entertains with a bubble-blowing fish. Soon there are bubbles everywhere, just waiting to be popped!
