Fireworks are stationary when the level starts. To activate them, they must be damaged. The most common way is to hit them with a Bird, however they can also be activated when a structure or a block falls on it and causes enough damage. However, if a White Bird's egg or Black Bird's explosion reaches near the Firework, they might explode at the same spot without flying. The firework usually goes in the direction opposite it was struck or in the direction it was facing, however occasionally they go in a random direction. The also can either fly in a straight, curved, or a zigzag line (as shown by the trails of smoke clouds they leave behind) and explode after about a second they are activated. Every bird can destroy it.
- Because Chinese fireworks are used in similar fashion to missiles in film, they are usually mistaken for missiles.
- They also appear in the background of Mooncake Festival.
