No. 6 Wrench

A No. 6 Wrench is an item that is required to get a Banana Bird Cave in Donkey Kong Country 3: Dixie Kong's Double Trouble! Dixie and Kiddy Kong obtain this item by going to Barter's Swap Shop and trading a Mirror for the Wrench. This item is needed for Björn's broken chairlift in Razor Ridge. By giving him the wrench, he can fix the chairlift and the Kongs can access the Banana Bird Cave on the other side.
