The Bomb Pass item is an item that allows the player to walk through bombs.
This item prevents the player from being boxed in by bombs, whether by an opponent or by their own bomb on accident. It makes escaping easier and they can plan quicker routes without being hindered by the placement of bombs. An important thing to note is that this item does not make you invincible to the bomb's explosion so be careful with your timing around bombs.
This is an item for 1 player mode most of the time, and it rarely appears in multiplayer, a player may use cheat codes to enable it in multiplayer as well.
