The Bomb Shopkeeper is a small elephant-like creature that has a talent for constructing bombs in A Link to the Past. He owns the Bomb Shop in the Dark World, exactly where Link's House appears in the Light World. He appears to have a cold that will not go away, as he is always sneezing.
When Link first meets him, he is working on building the most explosive bomb ever, but it takes him some time. So, at first he sells only regular bombs, but later, when Link has recovered six of the crystals, he sells a Super Bomb that allows Link to access the Mysterious Pond at the base of the Pyramid of Power.
