The Scuba Gear (さんそボンベ, Oxygen Cylinder, in Japan) is an equippable item that appears in Bomberman Quest. When it is equipped, it prevents Bomberman from taking damage underwater. It should be equipped before Bomberman enters an underwater dungeon. It can also be used to walk across bodies of water in the overworld.
