Pretty sure this is the last one of these. We didn't actually watch it to make sure, but the trailer shows one of these things making it into outer space somehow, which is usually the last gasp of a dying series before descending into direct-to-video hell waiting for a resurrecting reboot later (Leprechaun, Friday the 13th). Good news for the young ones, though: If they've been craving jokes based on the concept of sloth nipples, that thirst will be slaked.
