Ooccoo for Code-Code Puffs!
Game: The Legend of Zelda: Twilight Princess
You know that weird cloned-chicken-you'd-never-fry-and-eat-unless-maybe-you-were-blowed-off-that-Hyrulian-piff thing named Ooccoo? Well, that's the HTML code (#00CC00) for the color of Link's dress tunic in the first Legend of Zelda. Which makes this a FUBU Easter Egg: made by devs, for devs. Also, popular only in Africa.
