Isaac is a hedgehog who has only ever been alone – and that is the way he likes it. One day an apple falls from a tree and sticks onto the spines on his back. He wiggles and jiggles, but he cannot get it off. As he struggles to remove the apple, help comes in the unexpected form of a donkey who cannot reach the apples which fall outside of his paddock. Isaac learns that it is better to have a friend and to be helpful than to be on your own all of the time.
