While you have fun in the Interactive Story or you practice playing with the Mini Games you win ‘Gems’. They keep accumulating in your avatar’s score. You can use these gems to customize your characters with brand new garments and accessories.
You can also face the Challenges, Medals and Missions that you will find in the shelves at the sitting-room. If you see an animated exclamation point close to the shelves you’ll know there are pending rewards to activate to your avatar!
