I can't think of a name for this chunky beast, so I just refer to him as "Chubbs".
Chubbs lives a simple life, and what would you expect from a tiny-brained organism. Every morning, when the sun warms his body and gets his cold-blooded veins moving, he knows what to do: hunt for prey. For Chubbs always thinks he's hungry. Do not ask why; You and I know he's got quite the beer belly. But Chubbs does not know any better. He awakens each day and thinks, "Today is a wonderful day to find food." And thus is the life of a dinosaur-dragon-thingie with a brain no bigger than a walnut.
