Donkey Kong Bananza is a 3D action platformer where you can dig holes, build bridges, and experiment in other ways as you burrow through various whimsical worlds on your way toward the planet core. Nintendo was so happy with its deformation tech that it decided to spin it off into an entirely separate artist mode.

There are three Banandium Gems in the Nostalgia Country Ancient Ruin. Two of the golden bananas will be found as you progress through the level with one about halfway through the level and the other at the end. However, before you venture off, the most difficult Banandium Gem is actually at the very beginning of the challenge.
