Bomb Arrow

The Bomb Arrow is a combination of the Arrow and the Bomb (a Bomb that is shot) that appears in Link's Awakening and Twilight Princess and Link's Crossbow Training. It also appears in Spirit Tracks.. It is essentially an exploding arrow.

Link's Awakening
To use a Bomb Arrow in Link's Awakening, equip the Bow and Bombs, then press both buttons at the same time.

Twilight Princess
To use a Bomb Arrow in Twilight Princess, move the cursor to any variety of bomb and press Z on the Wii version or L on the Gamecube version to assign Bomb Arrows to a button. Note that a bomb arrow can detonate and hurt Link just like a Bomb. Bomb Arrows consume both a single bomb and a single arrow per shot. They are useful when attempting to blow up far-away rocks. But be careful: if you hold the Bomb Arrow to the bow for too long, the bomb will explode and you will take damage.

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

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.
