I got the idea when I read that Miyamoto borrowed the Balloon Fighter physics for SMB's Water levels. Then it hit me that Balloon Fighter could almost be a "joke" character like how Dan is in the Street Fighter series. Here's how his gameplay would be adapted: Balloon Fighter will start with 2 balloons (full health). The only powerup is a Balloon which appears when he only has one. Other times the balloon would only give points. He can always break bricks due to his helmet. He's vulnerable to all enemies that Mario can't stomp. Potential skins would be Player 2, Alice from Balloon Kid, Tingle, and possibly Villager.
