The Bubble Bomb takes the form of magenta bubblegum puddles splatted on the ground that emit bubbles, both as an icon and on the tracks.
In gameplay, the Bubble Bomb can only be obtained at random from Item Boxes by Vector. As with most other Items, Metal Sonic can also use the Bubble Bomb if he uses the Steal Item to steal it from the aforementioned user.
Once obtained, the player can utilize the Bubble Bomb by pressing its icon on the bottom of the HUD. When used, the Bubble Bomb will drop its bubblegum puddles some distance ahead of the user's current location on all the lanes that the user is not currently on. If a playable character, including the user themselves, touches one of these bubblegum puddles, the player's screen will be be obstructed by pink bubbles, thereby slowing their character down and preventing them from using power-ups in the Item slots on the bottom of the HUD. This power-up lasts for a short time, but it can be ended prematurely by tapping the Bubble Bomb's pink bubbles on the screen to make them pop. To avoid the Bubble Bomb, the playable character must either jump over their bubblegum puddles or run in-between them.
The Bubble Bomb can also be upgraded by leveling the user up to level 4, 10 and 16 respectively. For each upgrade, the number of bubbles created when touching a bubblegum puddle will increase, with fourteen being its maximum.
