In Paper Mario, the Crystal Ball is only needed to help complete one of Koopa Koot's favors. Mario needs to obtain an autograph from Merluvlee of Shooting Star Summit but she needs her Crystal Ball back from her sister Merlee who lives in Dry Dry Outpost. After Mario retrieves the Crystal Ball, he can give it to Merluvlee to get her autograph which then must be brought to Koopa Koot to receive three Star Pieces.
