Sheldon the Ammonite

Sheldon the Drunken Ammonite is the Stoner of the group. He can also hold his liquor quite qell, in addition to taking SuWater (You know the water that comes out of Hydrothermal vents? In my world, sea creatures use that liquid like weed). He is also very old, about 100 years old, but acts like a frat boy.
