Cake

Cakes are Items in Birdday Party. They are worth 3000 points when destroyed. In the latest update of Angry Birds, a new exploding cake appears in which when hit, it turns into frosting-like balls, similar to TNT Crates. But they don't explode. Also, in the current version, it won't award you points.

On Angry Birds Seasons, they also appear, worthing the same number of points.

They also appear in Angry Birds Friends, where are more found commonly, they worth 5000 points when destroyed, there are alot of variations of the cake.

On Bad Piggies, they are used to feed King Pig.
