Barter

Barter is a member of the Brothers Bear who appears in the game Donkey Kong Country 3: Dixie Kong's Double Trouble!. Barter operates a swap shop in the Northern Kremisphere overworld, just to the west of K3.

Barter just so happens to be in possession of a No. 6 Wrench. Although Dixie and Kiddy Kong have no use for a wrench themselves, Björn of Razor Ridge will reveal that he lost his No. 6 Wrench, and will ask the Kongs for their assistance in finding it. While Barter will be reluctant in parting with the No. 6 Wrench, the Kongs can pry it away from him by purchasing the Mirror that Bazaar sells for fifty Bear Coins, and trading it to Barter in exchange for the wrench.

Baffle also needs the Mirror to help him solve a puzzle, which will lead the way to a Banana Bird Cave. Should the Kongs wish to purchase back the Mirror from Barter, they will have to pay him ten Bear Coins for it. However, this is purely optional, as the Kongs can solve Baffle's puzzle without his help.

Trivia
In the original Super Nintendo version of the game, Barter's swap shop will appear to be mirrored while he is in possession of the Mirror. This does not happen in the Game Boy Advance remake.
