Barnes

Barnes is the owner of the Bomb Shop in Kakariko Village in Twilight Princess. He panics easily and his kind of a blabbermouth but all in all he's a great guy.

Inside his store, he sells:
 * Regular Bombs: these multipurpose bombs are the default and the very first shipment of bombs Barnes recieves 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 recieves 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 arros to create bomb arrow as well.
 * Bomblings: Oriinally seen in the Forest Temple, Barnes recieves a supply of these after Link completes the Arbiter's Grounds. 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.
