Walter the Whale is a cute little amigurumi project. You can crochet him im an evening with only some left over yarn and two black eyes. (Stitching on the eyes instead of plastic one is also perfectly fine.) Walter will do great as a key chain. Or you could make multiple whales to put them on a mobile above a crib. They look great in every color. Before you know it you will have a whole rainbow of whale lying around ;)
