Each time you brush, go to the zones you are shown. Your toothbrush becomes a joystick: if you brush your teeth well according to the diagrams, your character will collect coins and jewels during their trip.
Once you have chosen Go Pirate! in the Kolibree application, start the game using the button on the toothbrush.
Press the button again to pause the game.
If you want to restart brushing your teeth after pausing the game, just push on the toothbrush button again.
When the brushing game is over, the toothbrush will stop by itself without you having to press the button.
