ゥゥ] has no specific habitat because it was never programmed to be in a specific area, nor was it ever programmed for the player to find it. Since it only exists in Generation I, it must exist in the Kanto region. It has no habitat relating to the Mew glitch. Theoretically, it could also exist in some Glitch City-like location.
