Conker's Pocket Tales
Conker's little known first adventure, Conker's Pocket Tales is a top-down platformer for the Game Boy Color, developed by Rare, and released in 1999. Unlike it's more well-known sequel, it's kid-friendly and much more in-line with Rare's other Platformers like Donkey Kong Country and Banjo-Kazooie.
