Pitter-pat! Pitter-patter, pitter pat! Little Hedgehog is delighted when he wakes up to find it is raining. At last he can try out his lovely new raincoat, hat and boots, and his sparkly umbrella. But soon the rain gets faster and the wind gets blowier and Little Hedgehog's rain day turns into a great big adventure!
