J1 is a traditional monster-under-the-bed and he's been doing nicely thank you, until he gets assigned to single dad, J2's kid. J2 doesn't believe in monsters but he teaches his child to use a BB gun to scare off any monsters. J1 sticks around intending to show him just how scary he can be. It's hard to be noticed when nobody really believes in you and the longer he stays the more he wants to be the monster IN J2's bed.
