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.

Waimefo arrived at the cave as the third dino on a sunny day in the summer 09. As the third dino, he got much attention when he was young and even though he wasn't a dragon, he was treated as one. Though "he" isn't the right thing to say about this dino, since no dino's gender is known, but all think Waimefo is a male since he acts as many of the other males in the cave do, so for all of them, he's their big lad.

Waimefo is really shy, but at the same time he's a curious dino. He's kind and tries to help others as much as possible; which makes the other dragons and dinos like him very much.
