Who the last mouse left, who lost. Features: Just press the mouse bubbles down and they make a slight popping sound; then turn it over and start again! Infinitely reusable and washable, too. Non-toxic, tasteless, it will not cause any harm to humans and pets. Bright colors and pleasant sounds are sure to please any child. Perfect gift for your children or friend.
