Birdday Party 18-1 (or Birdday Party Cake 2 Level 1) is the two hundred eighty-sixth level of Angry Birds (if you don't count the bonus levels) and is the first level of Birdday Party. It is the debut level of the Orange Bird in Angry Birds.
For this level, use the Yellow bird at the foot of the left tower. Then use the Orange bird just above the TNT in the middle of the level. If the bird is going past the TNT, be sure to expand it manually to ensure its detonation.
This level is almost the same, except one Orange Bird 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, 2 Yellow Birds are in Orange Bird's introduction level.
- In Birdday Party Cake 4 Update (11 Dec 2013), This level has one more Orange Bird.
