Lights out at the sleepover, and everything under the bed has decided tonight is the night. Sock monsters, dust bunnies and the wardrobe thing come out in waves and walk straight at your pillow fort. Aim the dart blaster, fire, reload, and try not to be empty when the fast ones arrive. Between nights you have a few hours before Mum checks on you: spend them rebuilding the fort, raiding the toy box for a bigger blaster, or waking up more mates to hold the line with you. Every mate awake is more hands tomorrow. Nothing carries over unspent.
