A large marine monster somewhere between a fish, a mammal and an insect. They say that it is actually colored white, and no one knows how it turns pink again. It has a large horn on its head like a narwhal's that grows longer as it becomes more powerful.

My Monster Rancher "Its lovely face is popular among girls. Some would call it the "Princess of the Beaclons" because it's decorated with hearts and works to increase the length of its horn." Rollbeat MMR
