Mischief Maker by Kevin MacLeod
Hey buddy, wanna buy a ferret? How about a trained ferret? Okay, I didn't really train her... she just has a predisposition to things. She stuffs squirrels into boxes, feeds them sugary treats and then empties the boxes though mailslots. Well, if you're not going to buy her, how about some nails... to keep your mailslot closed.
