DKC Atlas Forum

Doees anybody have this commercial? It starts with DK beating his chest when a purple atomic explosion suddenly goes off in the distance. Donkey ducks for cover and the shockwave hits him, but no immediate effects happen. DK then stands back up and starts to flex his muscles when all his fur falls off in a heap. Donkey notices and moves away, embarassed. The rest of the commercial is spent advertising the game and the new console color of the GBC itself at the time (related to the explosion earlier).

I found this by doing a simple search on YouTube. It's not exactly as you describe, but it is the official Nintendo DKC commercial for the Game Boy Color.
