Barnes

Barnes is the owner of the Bomb Shop in Kakariko Village in Twilight Princess. He panics easily and is kind of a blabbermouth but all in all he's a good person and at times is rather funny.

Inside his store, he sells:
 * Regular Bombs: these multipurpose bombs are the default and the very first shipment of bombs Barnes receives upon reopening his shop. Although Link can have up to 30 bombs per bomb bag, these bombs cannot be used underwater. Special to Twilight Princess: these bombs can be used along with arrows to create hybrid Bomb Arrows, used to destroy elevated loose rock, or aerial enemies.
 * Water Bombs: Right before Link is required to venture into the Lakebed Temple, Barnes receives a supply of these. Unlike default regular bombs, these are specially designed to be used underwater, as their watertight leather covering keeps the bomb igniter from the water. These can be used on land and hybridized with arrows to create bomb arrows as well.
 * Bomblings: Originally seen in the Forest Temple, Barnes receives a supply of these after Link completes the Lakebed Temple. Bomblings are used for far away explosions, as the bug, when targeted on an enemy, rock or other point of interest, will follow/walk up to the object and destroy it, similar to some sort of homing device. These, however, cannot be hybridized with arrows, and can only be used on land.

Trivia

 * Barnes also bears a resemblance, at least in terms of hairstyle, to Bomb-Master Cannon, the bombseller from The Wind Waker.
 * Barnes's name may be a pun on "burns". In the European French version of the game, his name is Crahmé, an obvious pun on the French slang "cramé" (burned).
