You control a mouse, who weaves his way through a tricky maze of doors and corridors, munching cheese bits. His journey is made hazardous by hungry cats. By eating dog bones, the mouse temporarily turn himself into a dog and chase the cats. Or, he can go through a secret tunnel to escape, or open and close groups of doors to change the maze. But watch for the hawk that swoops down on the mouse, in and out of his dog disguise! Will your mouse make it through the maze -- or be a snack for the cats or the hawk?
