Flower

Flowers are a game mechanic introduced in Angry Birds 2.

Gameplay
Flowers act as "cannons" that shoot out anything that falls into their open petals, regardless of their size. Objects that can be captured and shot back include blocks, pigs, or even the birds themselves. However, flowers cannot hold more than one object at a time. There is roughly a one second interval in which the flowers reopen themselves, ready to recieve more falling debris.
