That, my friend, is a fine example of redneck art. Behold the Assquatch, or the delicate art of shaping a deer's butt into a face of the monster.
Masterry of the art is attained, apparently, when you can shape the anus into lips: Link Assquatch blog - via YesButNoButYes

I am amazed at how many people can't figure out what it was originally.
