Bunny-saurus Rex

The Bunny-saurus Rex was the result of an old project that Dr. Wu never talks about. He wanted to give rabbits some defense against other animals such as foxes and wolves, so he mixed the rabbit genes with genes from a dinosaur that he thought was a Stegosaurus but later turned out to be from a T. Rex. The end result was terrifying and one individual of the new species managed to escape and disappeared into the woods. No one has seen it since then.
