To "win" a Bongo Session, tap as fast as you can on the bongos in the allotted time.
Bongo Power is displayed at the top left, time remaining is displayed at the top middle, and the number of rewards you’ve earned is displayed at the top right.
Each time you fill the bar you will earn more rewards in the Legendary Chest for completing the Episode.
TIP: You can tap faster if you use multiple fingers!
Increase your Bongo Power by upgrading certain Characters. See Character list.
