The Triple Bomb can be found in Caron Forest.
The Triple Bomb is, in essence, a powered up version of the initial Regular Bomb. When used, Tails will throw the bomb and it will explode, causing three simultaneous explosions at once when it makes contact with something. This gives the Triple Bomb a wider explosion radius that even shakes the screen upon the impact.
Like the Regular Bomb, the Triple Bomb can be used whilst jumping, allowing it to travel further. If used whilst flying, the Triple Bomb will drop underneath Tails, allowing the player to attack overhead. The Triple Bomb can also be used whilst crouching, though this reduces its range.
