Bombs resemble the bombs from the Toxic series. It appears as an orange circle with eight orange spikes pointing out along the circumference. In the middle of the bomb is a timer which counts down from three seconds once the bomb is dropped.
When the player presses the spacebar, the submarine will drop a bomb from its back, which will explode on impact with an enemy or if it has been traveling downward for three seconds, whichever comes first. The player can use an infinite number of bombs to help destroy any enemies.
The damage the bombs deliver depend on the enemy the submarine is trying to destroy.
