A Rare Orb is a very important item in Donkey Kong Country Returns. They are orbs found in various colors (depending on what temple the player is in) that are held in secret temple of each of the game's eight worlds. The secret temples have to be unlocked first by collecting all the hidden K-O-N-G Letters in each world. In order to get a Rare Orb, Donkey Kong and Diddy Kong must get past all the obstacles and enemies in the temple. Once all eight Rare Orbs are collected, they unlock the entrance to the Golden Temple.
