Bomb Arrow

The Bomb Arrow is a recurring item in the, first appearing in Link's Awakening. It is essentially an exploding arrow that results from combining bombs with arrows. They are shot like normal arrows, but when the arrow reaches its target, the bomb explodes.

Link's Awakening
In Link's Awakening, bomb arrows are not required to complete the game. Link can shoot them by equipping both the Bow and Bombs and using them at the same time.

Twilight Princess
To use a Bomb Arrow in Twilight Princess, the bow must first be equipped, then the R Button (for the Nintendo GameCube version) or the Z Button (for the Wii version) must be pressed when any kind of bomb is selected in the inventory screen. Bomb Arrows consume both a single bomb and a single arrow per shot. They are useful when attempting to blow up far-away rocks, which becomes necessary when Link ventures to the Lakebed Temple. Should Link hold the Bomb Arrow to the bow for too long, the bomb will explode and the young hero will take damage.

Spirit Tracks
In Spirit Tracks, Bomb Arrows are not a usable item. Instead, they are fired from Bulblins on the overworld while riding the Spirit Tracks.

Link's Crossbow Training
Bomb Arrows also appear in the spin-off game Link's Crossbow Training. They can be used by holding the trigger on the Wii Zapper to "charge a shot".

Trivia

 * The Bomb Arrow may have been inspired by the explosive arrows that Rambo uses in the movie Rambo: First Blood Part II.
