At each brushing, brush the areas as displayed. Your toothbrush becomes a joystick: if you brush your teeth as shown, your Rabbid will run faster down the race track and will catch the stars placed above the obstacles.
To start the race, put toothpaste on your toothbrush, place the brush in your mouth and press the button on the toothbrush.
Follow the brushing areas on the smart guide at the bottom left of the screen.
At the end of the game, the toothbrush will stop by itself, with no need to press the button again.
