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.

Chromatosaur is a Yellow Dino who was snagged by his owner as an egg with the help of AshenRoot the Vine. Not particularly bright, Chromatosaur can't seem to get used to his long neck, and often bumps his head while walking into caves or caverns. As a hatchling he managed to literally tie himself, or rather his neck, into a knot. It took the combined efforts of his owner, all the dragons in the family, and quite a few other dragons who had been called in to help to untangle him. Despite his lack of intelligence, Chromatosaur is a kindhearted and gentle dragon, willing to help lift or retrieve objects placed out of his owner or the smaller dragons' reach and put up with hatchlings using him as an oversized see saw.
