The Firework Flurry's takes the form of a blue, staff-shaped Roman candle with a yellow rim and yellow five-pointed stars on it. In gameplay, it becomes a projectile are that is colored either red, yellow, or blue.
In gameplay, the Firework Flurry can only be obtained at random from Item Boxes by Lantern Silver. As with most other Items, Metal Sonic can also use the Firework Flurry if he uses the Steal Item to steal it from the aforementioned user.
Once obtained, the player can utilize the Firework Flurry by pressing its icon on the bottom of the HUD. In addition, when obtaining the Firework Flurry, there is a chance of obtaining up to three Firework Flurries to use in the Projectile Item slot on the HUD from a single Item Box. When used, the user sets loose the Firework Flurry's shot, which will travel down the lane it was deployed on in front of the user until it hits either a rival character or obstacle, or it wears off. The shots come in three colors (blue, red and yellow), but the color is chosen at random. In addition, the differently-colored shots will have different effects on the rival character they hit:
Red: Rival characters that make contact with the red shot will take damage, causing them to lose Rings and slow down momentarily.
Yellow: Rival characters that make contact with the yellow shot will be stunned, causing them to lose Rings and stop moving for a moment,
Blue: Rival characters that make contact with the blue shot will lose Rings and be frozen.
To avoid the Firework Flurry, the playable character has to either step out of its shot's lane or jump over it.
The Firework Flurry can also be upgraded by leveling the user up to level 6 and 12 respectively. For each upgrade, the player will increase the damage dealt with the Firework Flurry.
