The Dink Network

you get the yellow key from the pimp guy trying to sell you women (standing in front of a yellow door on the green-recreation level..4?). You have to take his "dance challenge" thing which only appears after you talk to him at least once- I missed this whole part and had to restart the game because I killed him before I realized he had the key. Um, save the game before you do the challenge.

What level is that riddle on?
