He first appears on the top floor of the town hall in Safen. You have to pick up the lewd guestbook on the table, and then talk to the pink dragon, and say that he's gay. Then he will appear at the Bangers club in the Gloomy Forest, same procedure. Then he appears at the Western Island beach, same thing here. Then there's a random chance he'll be at the glory hole, when the number above the right door is a 4, it's him.
