create a creature

This is my character I made for this class: Incredible Gassy. He lives in the Arctic and kills animals using his gas and by jumping around with his strong legs. He swims for fish using his gas to help him move through the water or snow. He is like a human but has evolved to live in the snow, with extra blubber and his own clothing made from seal skin. His diet is mostly penguins and seals. There are no others of his species.
