Spike, a little hedgehog, has always had impressive prickles. But one morning, after a particularly scary dream, he wakes up completely bare! Oh no! Feeling very embarrassed, he goes in search of something to cover himself, from a paper lampshade to a tea cup to a very stinky sock. But nothing stops the other animals giggling at him. Poor Spike! Then he discovers a big bunch of balloons, which takes him across the world and ends in a very satisfying POP! and a very prickly party.
