Craig the Crayfish lives in a snug little nook under a wobbly driftwood table, where something lovely is always about to happen. He’s the kind of friend who is always ready for a surprise visit, greeting everyone with a cheerful “Oh good, you’re here!” Craig spends his days pottering along the seabed, collecting tiny treasures, shiny shells, curious pebbles, and the occasional mysterious object that no one quite recognises. He doesn’t mind what they are, only that they might be useful for something wonderful later.
