The Pile Bomb or Piled Bomb is a cyan bomb from Bomberman Story DS. In the game, you can unlock in the shop these bombs by finishing the first planet, in the second planet you have to destroy some soft blocks. To use it you have to push R or L and move to the bomb. You can have a max number of ninety-nine Pile Bombs.
These bombs work like a normal bomb, and they don't have very notable changes. If the player piles two Pile Bombs, the second bomb, instead of bouncing, will disappear, and the first bomb will grow larger. You can pile a max number of five Pile Bombs. If you pile a sixth bomb, the bomb will just stay on the floor.
