While most rexes you encounter will be ordinary, there is one special Rex that you may come across: Derp. “Derp” is an immortal, world hopping rex. He can be found on any world. Derp will always incarnate as a white, male rex with a gray pattern on his back. The incarnation can be any level. What sets this apart from normal rexes is that any survivors viewing him will feel compelled to refer to the rex as “Derp.” If tamed, the survivor will end up naming the rex Derp. Have you ever encountered Derp?
