Finally, after much feeding, the baby has grown into a full Dino! Dinos can eat almost anything, including things with spikes. In order to do so, they must have very tough stomachs. Yellow Dinos have very long necks, which they use to reach and eat food located high off the ground.

Jasper is taller than typical Yellow dinos and can reach the canopies of trees with much ease. Though he is really neither male nor female, he is referred to as male. Jasper's sheer size tends to intimidate young hatchlings until they realize he is just a big goof who loves to play. He seems to be afraid of fire, however, and will promptly run away for any dragon creating flames.
