While you are playing the game, you may notice Tibby in the bottom-right corner of the screen when the game is loading. However, if you've already bought all the shop games, you will automatically receive 30 coins for each extra Flow Ball in your possession by talking to Saffron. Usually, Flow Balls unlock Rhythm Games from the shop. It's possible to earn a Perfect in the unlockable Quiz minigame by intentionally getting the first practice question incorrect. This enables you to play drums with the song (the D-Pad, ABXY and LR buttons create different drum sounds.) To exit the player during this mode, you must press and hold L, R, and B at the same time for about three seconds.
In the Caf Museum, before selecting a song for the music player, hold L and R while pressing A.
