Bombling

Bomblings are small, insectoid explosive creatures that grow out of the ground within the Forest Temple in.

Location
First appearing as unkept (yet usable) explosives, Bomblings can later be purchased and stored as a normal Bomb.

Eventually, in Kakariko Village, Barnes, the bomb salesman, receives stock of these specialty bombs that can be purchased and used outside of the Forest Temple area. Link will receive a letter after he completes the Lakebed Temple, indicating that the owner has stocked up on Bomblings.

Uses
The item variety of this creature is very similar to the Bombchu, only that they cannot go up walls. Link will immediately become acquainted with this variety of bomb, as he must use them to complete the Forest Temple. The Bombling will crouch when approached and, if not picked up or attacked, will start a weak string of attacks upon Link that, over time, will cause accumulating damage.

These insects are invaluable within the Forest Temple because of their ability to become temporary bombs when startled. However, if these bomb insects are not picked up or destroyed within their "countdown" time span, they will self-destruct. On several occasions, Link will find the appearance of these bomb bugs very useful, as in some areas, blowing up a rock in the way is the only way to proceed to a new section of the dungeon.

The temple boss, Diababa, can only be successfully destroyed with the aid of these bomb bugs, along with the Gale Boomerang and a familiar monkey.

When used, these bombs will run in a straight line until they have contact with another object, at which point they will explode. If they near an enemy, they will follow it. 10 Bomblings can be held in each bag until Link receives the bomb bag upgrade, which allows him to hold 20 Bomblings per bomb bag. These bombs cannot be used underwater.

Unlike standard Bombs and Water Bombs, Bomblings are entirely optional as an item, as opposed to their use in the Forest Temple. At no point in the game is Link required to carry them in order to proceed, and there is no task in the game, mandatory or not, that can only be accomplished with Bomblings, again excluding their non-item appearance in the Forest Temple. This is in part because of the presence of Bomb Arrows, which can go anywhere Bomblings can and many places they cannot.

Trivia
