Mark Stevenson posted an image recently that appears to show Donkey Kong wearing a mining helmet in Donkey Kong Country. The helmet’s headlamp was apparently intended to light dark cave levels in the game, but was later scrapped by the development team.
The image was a render of Donkey Kong wearing the helmet in an earlier stage of development. The helmet was later replaced by Squawks.
