Donkey Kong Junior is a 1982 arcade-style platform video game originally created by Nintendo, and ported to the Atari 2600 by Coleco. It's a sequel to the popular original Donkey Kong arcade game, with the player this time controlling Junior, Donkey Kong's son, instead of Mario (who is now the villain of the game).
