The toilet leaking seems like a little too much effort for me, but otherwise I’m on board. Don’t forget moving their small and easily misplaceable objects when they set them down. Maybe just around the room a little bit, like putting their phone on their seat when they get up instead of the arm of the chair where they left it.
At first I was looking at the skeleton backwards, like some kind of xenomorph with a weird head shape and a long tail.
