The ragged tail was inspired by Japanese paintings of stormy oceans. When the Japanese artist wants to make a breaking wave frightening, he draws it like hostile claws rather than in the softer Western way. If you have a boat hanging on top of a wave in a Japanese painting, you know it is going to go over. These are waves to die on, not surf on. The normal way to draw the tail of any animal, from a squirrel to a dog, is to make it round and soft like the Western waves.”
