Mau

This giant dragon is a kind of dragon called a "mountain mouth" it swims through the ocean, catching more fish than a normal dragon could eat in its life. It swims for days on end, filling its mouth with fish, and when it's mouth is full, it swallows the fish into its monumental belly. This one found itself on a beach, sunbathing and eating the stuff that washes up there, but many dragons trick mountain mouths like him lots, trying to steal their fish straight from their mouths. You are a dragon who wants to steal his fish, as you can't seem to find any in your usual fishing spots.
