Pee Monster
Nobody was allowed to get up in the middle of the night to pee or else they might be hunted.
The creature lived under Jacob’s bed, the farthest bed from the door. For those who occupied the beds nearest the door, and who were fleet footed, they managed to make it to the lavatory. Sometimes.
Billy Squire was the victim that night. A new boy and a sleep walker. The boys called his type A Midnight Snack. He lifted himself out of bed and wandered in circles. Easy prey. A grumbling hiss rolled out from under Jacob, his bed shaking as the creature sensed movement and tickled the air with its forked tongue.
The boys never spoke out, some feigned sleep, least the beast turn on them. Billy made it to the cookie jar in his dream when the creature unfolded itself and slithered out from underneath the bed, its barbed hairs snagging Jacob’s blankets and dragging them behind its oily body.
In one bite the creature grabbed Billy’s leg and dragged him back underneath the bed. As it ate, whoever had to pee, did.
