Boomer (Donkey Kong Country 3: Dixie Kong's Double Trouble!)

Boomer is a Brother Bear who specializes in explosives in Donkey Kong Country 3: Dixie Kong's Double Trouble!. He is located in the lost world, Krematoa, where he appears in his own location, Boomer's Bomb Shelter.

Boomer wears an orange vest and a yellow construction hat. His official artwork also shows him wearing a pair of black shoes. In the Game Boy Advance remake, Boomer's appearance was altered, along with his location. Boomer is now wearing a white undershirt (like that of Brash's) and a red construction hat.

History
According to Boomer, he explains that the other residents of Northern Kremisphere banished him to Krematoa, deeming him "too dangerous" (given his love for explosives). Unlike some other Brothers Bear, who provide their service in exchange for bear coins, Boomer only accepts Bonus Coins for currency. By default, every level in Krematoa has a pair of rocks blocking the path, and Boomer charges 15 Bonus Coins (18 in the Game Boy Advance remake) per each of the first four levels. For the final level, Rocket Rush, Boomer charges 25 Bonus Coins (26 in the Game Boy Advance remake). After the rocks blocking the path to Rocket Rush are detonated, Boomer has no more explosives that he can use.

After the Kongs pay Boomer, he uses munitions to blow up of the level's rocks, allowing the Kongs to access it. When Dixie and Kiddy complete a level, they obtain a cog. By returning to Boomer's Bomb Shelter with the cogs, Boomer places them on a machine that has been in his bomb shelter ever since he moved into Krematoa.

If the Kongs have enough Bonus Coins for two or more levels, then Boomer forces them to pay for as many of his "specials" that they can afford at once. Boomer then blows up a number of rocks blocking the path to the levels, based on how many of Boomer's "specials" they purchased. In the Game Boy Advance remake, the Kongs can only pay Boomer for one level at a time. After Boomer detonates the rocks, the Kongs exit from his bomb shelter and must revisit him each time to have him blow up the next level's rocks. If the Kongs attempt to pay Boomer fewer Bonus Coins than he requires, he reprimands them and claims someone tried it before, whom he implies was sent up into space.

When all five cogs are placed on Boomer's machine, the dormant volcano in Krematoa reactivates, and Baron K. Roolenstein's Knautilus rises in the central lake.

If the Kongs revisit Boomer, a fan appears on his countertop, blowing on his face due to the temperature increase caused by the volcano's reactivation. He claims to have bought the fan from Bazaar's General Store; this dialogue and the fan itself is absent from the Game Boy Advance remake.

Trivia

 * In the SNES version, if the player enters the cheat code "WATER" to automatically collect every Bonus Coin in the game and goes to Boomer, he will be surprised that the Kongs already have all the Bonus Coins.
