Alphabet Challenge Event

Alphabet Challenge Event is a limited-time event that requires players to collect letters in bubbles that randomly appear flying in the game. These are required in order to complete Apple Cookie and Soda Cookie's speech bubbles.

Players can check their progress by clicking the SURF button at the top right next to the Photo Challenge button. Once both the speech bubbles have been filled in, the player will receive 20,  10,000, and 5 Boost Sets. This event can be done in every episode with the exception of Ghost Pirate's Island of Coins.

The letters collected are not duplicate, so players may need to collect more than one letter to fulfill the letter. For example, players need to collect 3 A's to complete the A in the puzzle.

Like all other letter grabbing event, beside the available letters, there are also unused letters such as Q and Z that does not add to the progress of the event.

The letters are summing up into two different speeches: Apple Cookie says "SUMMER IS HERE!" while Soda Cookie says "SURF WITH US FOR A SPECIAL TREAT!" Therefore, the letters you need to collect are:
