Yellow

Yellow has the appearance of a Pterosaur but it is yellow showing many similar traits to the prehistoric creature. He looks like a prehistoric bird. He has an arrow like head with three pointy ends. he has sharp teeth located in what seems to be a bit like a beak, he also wears some sort of vest with a large metal propeller that spins when he 'takes flight'. His arms take the shape of wings, with two fingers on the end. It's assumed that these wings aren't very useful in flight, instead the propeller on his back allows this ability. He also has a small yellow tail. sometimes he can pick you up so you have to jump in a bouncy house to survive the fall damage.
