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. Green Dinos are the only type of Dino that is able to walk on two legs. This frees up their front two legs, which they use to catch and eat fish.

Hacia Atras is a kind of pet in this cave. As a dino it doesn't have the ability to communicate with the dragons, it just makes "Quooook!" all the time... When the dragons started being annoyed by this, they show it how to catch fish which is what Hacia Atras is doing most of its time now. Its name means "backwards" and hints at its looking over its shoulder all the time. Hacia Atras also spends some hours a week with Inkheart Paperblanks. The paper dragon likes the dino because there is no chance to see it spit fire.
