This came from a sketch i did last week. I imagine it to be an all-terrain animal. Something that can dive into the deep ocean like a sperm whale but boogie on land as well. Maybe it feasts on the fungus that grows under dead carcasses and debris on the ocean floor so it uses its tusks to move the item to get to the fungus. But it can't sleep in the water so it has to leave the ocean each night to sleep on land.
