This special type of bomb was first introduced in The Legend of Zelda: Twilight Princess. The Water Bomb retains all of the functionality of the regular bomb with the added ability of usage underwater. In order to do so, Link must be wearing the Iron Boots. The bombs can also be combined with the Hero's Bow to create an bomb arrow which explodes on contact. Bomb Fish are similar to water bombs, though they are simply struck and will then explode seconds later.
- An important thing to remember is that Link can only carry HALF as many Water Bombs as he can regular Bombs. Therefore, Water Bombs reach their peak of usefulness between the point they are first available and when Link gets the Master Sword.
