Toku?! What's That?

Toku - Meaning spiked whale. This thorny whale has a similar colour scheme of a killer whale, but with other features such as a narwhal horn, and excessive spiky fins, not only they are protections, they're for sensing nearby creatures. Due to it's excessive amount of fins, it's speed is slower compared to other whale-like creatures. It also has 4 limbs to help going on land temporarily to prey for coastline creatures.
