Multiple powerful birds and items, such as Red, Chuck, Bomb, Hammer, and the Disco Ball, help you with the levels. You can create the birds on a level by matching 4-5 matchables, or you can purchase them from the pre-level screen.

You can get a head start on a level by purchasing the bird boosters with gems from the pre-level screen. You can choose from Chuck and Red, Bomb and Red, or the whole trio. 

While playing a level, you can also purchase the Bomb, Hammer, and Disco Ball boosters by dragging and dropping them from the bottom of the screen to the game area. 

Hammer booster – it will cause damage to the item you drop it on.
Disco Ball booster – removes all the matchables of the color you drop it on.

Please remember that using a Hammer or Disco Ball does not use any moves.
