Now this might sound crazy, but how many programs or games have you seen where characters tie corpses to themselves to help with transport.
So small corpses like rabbits, crows, squirrels, spiders etc, can be turned into bound X corpse with a couple of pieces of string and then worn (Maybe limited to 5 or 6 small corpses)
Medium corpses like cougars, coyotes, wolves, (maybe deer?) require some rope and are limited to 2 or 3 to be worn
Large corpses like bears, moose, (again deer?) require a heavy stick and some rope and only 1 can be worn at a time.
