Squirrelopotamus 

Giant squirrels that roam New England during the winter months. They are impervious to the cold and seem to enjoy antagonizing bird-watchers by routinely emptying well-secured bird feeders. The squirrelopotamus is known in the scientific community by its Latin name, Sciurus hippopotamid.
