Magical ? It is an intelligent mouse, who can follow a line on the floor through its electronic eyes.Funny, isn’t it? You have to trace a winding road with a black adhesive tape on a white floor, and you can see how the mouse can go, perfectly following the black line up to reach the goal. It can also be activated by the sound.
