Giant Shrew 

Brandon 

It was technically a giant worm that lives inside an underwater cave. Plus if you make it mad the slanted spikes on its back will frill up. His hair is 6 sharp red strands as thick as your pinky in every direction. It is blue with a yellow stomach that has lines. I forgot to mention his spikes are red. But one of the main details is that his tail and face are sharp with razor like teeth.
