Ouch! by Ragnhild Scamell, illustrated by Michael Terry

From the back of the book:
Hedgehog has just finished building a cozy nest ready for winter when...Ouch! ...a juicy red apple falls from a tree and sticks in the spines on her back! And now Hedgehog can't fit into her nest. Oh dear! Squirrel tries to remove the apple but things don't go quite as planned and soon Hedgehog has a juicy red apple and three brown nuts stuck on her back. So Pig and Frog try to help too...
