Pooasaurus Rex 

A T- Rex, oddly combined with a Poo. It has the body of a T-Rex, and the head of a Poo.

A scientist was in the deep forests of the amazon, when he saw a Poo and T-Rex mating. The scientist came back a few months later, seeing a large egg in a nest. It was moving. the scientist walked over to it, and the top of the egg cracked open. A head of a child poped out. Scientist was confused. "Little girls dont come from eggs!" the scientist yelled. The small child came out of the egg with a dinosaur body! " I WILL CALL THIS A POOASAURUS REX!!!!" The scientist screamed.
