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.

Pewdie Pie, or Pewdie for short, is a young Yellow Dino. Found as an egg by Steve Duckbill the Green Dino somewhere in Sweden, he has no idea why he's a Dino or where he came from. However, he doesn't think too hard about this, as he is happy where he is right now. He is often found going on adventures to haunted castles, waking up in  unknown places in the future or past, exploring the forest outside his clan's cave, and various seemingly insane things. However, even through these normally terrifying events, he still finds a way to keep his sense of humor strong, even when he runs into his worst enemies; barrels. For unknown reasons, Pewdie absolutely detests barrels. His faithful companion, Stephano the Pygmy Gold dragon, is always by his side, along with Piggeh, a zombie pig that he found in the forest. He often refers to the other dragons in his clan as his "bros", and "bro-fists" them whenever he leaves to go on a quest.
