Hard Hitter is the 2nd Advanced Extra and the 3rd Expert Extra floor in Monkey Ball and Super Monkey Ball, as well as the 2nd Advanced Extra, 13th Expert Extra and 132nd Ultimate stage in Super Monkey Ball Deluxe.
Similar to Hitter, this stage features a flat, square-shaped platform with five bananas across from the starting point. The goal is in a large square wall, which constantly spins around and moves across the stage. It spins so fast, so being hit by it is an almost guaranteed fall out.
Do not move right away. Instead, wait until about 23:18-23:75 to move forward. In between this timing, it is impossible to miss the goal if you just go up. But If you miss the goal, then wait for it to come another time towards you and try again.
