Thunder Cove

Thunder Cove is an unlockable racing track in the game Diddy Kong Racing DS. Along with Meandering Mount, Splashdown Pass, and Strangled Shrine, it appears to be on Donkey Kong Island. Thunder Cove has what seems to be regular jungle with several trees and a short, bridged area of water. The course seems to be based off of the jungle and treetop levels in Donkey Kong Country.

It can only be unlocked by being bought from Taj in his tent. The track wasn't featured in the original game.
