Lulu and the Hedgehog in the Rain (5)

Lulu loves animals. She knows that the hedgehog she rescued isn't really a pet, but Lulu does want to make sure she's all right. And so the Hedgehog Club is born. Everyone on the street agrees to keep an eye on the little hedgehog and keep it away from the road. But come wintertime the hedgehog disappears! Where could she have gone?
