The Pit (1981)

Jamie wouldn't kill anyone...unless Teddy told him to! Twelve-year-old Jamie (Sammy Snyders) is one creepy kid...he has a perverse obsession with sex, his only friend is an evil teddy bear, and he's the only one who knows about the hole in the forest where he feeds raw meat to a ravenous pack of mutant troglodytes. Jamie will teach everyone a lesson: the kids who teased and bullied him, the mean old lady down the street, even his pretty new babysitter. Soon they - and his entire town - will face the flesh-eating horror of The Pit!
