Bing wants to make a big picture, so Flop finds him some chalks to draw on the pavement. Bing draws some stripy, spotty, zig-zag dinosaur but just as Bing finishes, the rain washes the dinosaur away.

Bing discovers a hole in his favourite yellow wellies, but he does not want to throw them away. He finds a way to recycle them into flowerpots - with help from Flop.
