In this event, your goal is to collect apples from the levels. To collect an apple you will need to break the block containing the apple icon. In order for the apples to be counted, you will need to complete the level successfully.
Once you have collected enough apples, you can go to the Birdie's Kiosk and use them to purchase different goodies, such as boosters, coins, or unlimited lives. The event ends after the timer has run out. You can see the timer on the event icon on the left side of the main screen, as well as on top of the Birdie's Kiosk.
