A four legs herbivore animal.

The male is agressive and likes to fight, and when it gets angry, the fur on its back hardens and turns into dangerous spikes. He is in charge of protecting the female.

The female evolves a different fur on its back to protect its baby, almost like a bed. She has colour that allows her to camouflage.

I had no time to do a background, and the preview is horrible, but whatever.
