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.

Initially found by dragon scholars as part of discovery trip regarding the reproductive habits of other mythological creatures, this Dino's egg was thought to be an infertile specimen which had been preserved. When it had hatched, the dragon in charge of inspecting the egg suggested they name it "Oops". After observing the hatchling's behavior, however, it was decided that his name should be Progency of Yoshis. This was done in tribute to the legend of the mythical breed of Dinosaurs who were said to have been able to fly, and who had aided two superhuman plumbers in a battle against a fearsome turtledino hybrid monster (which some humans, amazingly, had referred to as a dragon) in ages past.
