Look, bathrooms are gross to kids, which makes them the perfect stage for mischief. One night, have your elf “unroll” an entire roll of toilet paper across the hallway. Or better yet, have it sitting in the sink wearing sunglasses, holding a toothbrush like a microphone, singing into a mirror.
My personal favorite? The “toothpaste heist”. Squeeze a tiny bit of toothpaste onto the elf’s cheek, place a toothbrush next to it, and leave a note: “Tried to brush, got dizzy.” Your kid will laugh (and maybe actually brush their teeth more often). No promises on that last part.
