Hedgehog Rolls Over: In Autumn (Book 3) -- Raymond McGrath, Library Binding

Autumn is here! The air is cool and crisp. The days are getting shorter. And colorful leaves begin to fall . . . As Bird, Spider, and Worm enjoy the beautiful weather, a strange, spikey pile of leaves snuffles about. They help a pointy creature get free, only for her to roll right back up into a ball. Can the gang find a way to gain the trust of this shy friend? Or will this "spikey, dancing cactus" roll away for good?
