How to play: move with W A S D or the arrow keys, or hold the mouse / your finger on the house where you want to go. Hold Shift (or switch on 🤫 Sneak) to tiptoe: Uncle Grumble can hear you walking nearby, but not sneaking. Stand next to a pulsing 😈 spot and hold Space (or the 😈 button) to set up the prank. Hide in plants, cupboards and baskets. If he sees you for too long he shouts "HEY!" and you lose a heart. Every prank goes off when he walks into it!
