Bluster Barrelworks is a company in the Donkey Kong Country animated series. Bluster Barrelworks is the resident barrel-making factory on Kongo Bongo Island. Though Bluster Kong runs the factory, it is officially owned by his mother. Aside from Bluster, the only other employee is Candy Kong.
The grounds of Bluster Barrelworks consist of the factory itself, a helipad for Bluster's barrelcopter, a launch site for the Rocket Barrel, and a set of mine cart tracks, connecting the factory to the rest of the island.
After sending lumber in that is manufactured into a barrel, the barrels are sent down a conveyer belt inside the factory to Candy Kong, who either rejects them or accepts them (appearing to be a quality inspector). Barrels that are accepted are sent down one belt to be shipped, and those rejected are sent down the other belt and are destroyed. In the episodes "Bluster's Sale Ape-Stravaganza" and "Barrel, Barrel... Who's Got the Barrel," it is shown that the factory ships barrels using the Rocket Barrel.
