N/A (formerly Mine and Dine 17-15) Birdday Party Cake 2-2

Birdday Party Cake 2-1 (formerly Birdday Party 18-1) is the first level of Birdday Party. It is the debut level of the Bubbles in Angry Birds Classic.

3-Star Strategy

For this level, Chuck should fling to the foot of the left tower. Then, Bubbles should fly just above the TNT in the middle of the level. If he goes past the TNT, the player should inflate him manually to ensure its detonation.

Past Versions

This level is almost the same, except one Bubbles instead of two.


  • This is one of the few levels where already-introduced birds are featured in a bird's introduction level. In this case, Chuck is found in Bubbles's introduction level.
  • In Birdday Party Cake 4 Update (11 Dec 2013), this level was given one more Bubbles.
