Even stranger than the gameplay of Noby Noby Boy is the meta-game going on among all the players. Namco Bandai explains that "players collaborate to unlock new game stages." As players stretch "Boy" in their individual games, an entity known as "Girl" is growing according to the combined length of all the players in the world. As Girl reaches certain milestones, those stages will be unlocked for everyone around the world. It's not clear if that means they'll be available as part of the game or as DLC.
