Mutantis.

When an unscrupulous scientist drags his stepchildren out into the forest to use them as bait in the hopes of luring out a big foot, not even the team of hillbillies he hired can contain the horror they find: the horror of Mutantis! Only the adventurer Dr. William Fury may be able to stop the beast, but hope dwindles fast once Dr. Fury realizes that the monster is not only intent on murder but procreation as well. Could this be the end of the world as we know it? For the answer watch, Mutantis!
