3D Pocket Pool was at one point pitched to Nintendo as a Wario game titled Wario Pool. Developer Nick Pelling's website contains a GIF featuring the intro to the would-be Game Boy title, showing Wario sitting in his castle from Wario Land: Super Mario Land 3 and watching a sports newscast late at night. He then gets a telephone call from a reporter asking if he will be competing in a pool tournament the next day. Wario declines, saying he does not want any more "meaningless victories", until two new challengers appear on the newscast: a pair of literal pool sharks who insult Wario while being interviewed, motivating him to join the tournament and claim their heads as a trophy.
