Piff Grey MouseHide the cheese, as Piff mouse is small enough to find it. With her soft plush fur and beanbag interior, she sits perfectly next to the bed, her string tail behind her. The perfect size for some pocket or schoolbag love, if she gets grubby with too many cuddles, she can be popped into the washing machine, and with the Steiff label, you know she will be running around for years to come.
