Keys especially...those are the worst. Maybe Thimbletack likes the way they jingle or how they shine. I'm not sure what it is to be honest, I just know that every time I set my keys down, they reappear somewhere else later and the Minis swear they didn't touch them. So, since the Minis didn't move them, and I didn't move them, it HAS to be Thimbletack.
Thimbletack oh Thimbletack PLEASE give us our stuff back! And while you're at it...please quit taking it too!
