Sneakers: Small Heroes, Big Adventure (known in Japan as Nezumikusu: Have a mice day!) is a 2.5D action-adventure game developed by Media.Vision and published by Microsoft for the Xbox on February 22, 2002 (in Japan, as a launch title) and October 22, 2002 (worldwide). In the North American market, it was only released at Toys "R" Us stores.
