Dynabombs are an infinite supply of bombs that the player can lay at any time (s)he doesn't have anything else to lay. They explode in a cross shaped pattern, and may have strange results when they kill enemies. (For example, Yam Yams will only give off the center element of their pattern.)

This pick-up will increase the number of Dynabombs the player can put on the field at one time. This number starts at zero, so the player must pick up one of these to use Dynabombs.
