Whirling whippus

A bloodthirsty creature of considerable size from the folklore of American immigrants. He has a gorilla-like head and body, as well as huge front legs.

His unique method of getting food is dancing on the trail, usually at the turn of the trail, where he spins on his tiny hind legs. The speed increases until the animal becomes invisible, and the movement causes a strange humming sound that seemed to come from the trees above the head.

Any creature walking along the trail and not recognizing the sound will almost certainly fall into the danger zone and instantly stick to the substance in the form of syrup or varnish on the huge paws of the vimpus.
