Banks is the first stage of Advanced in Super Monkey Ball 2 (21st in Super Monkey Ball Deluxe), World 2-1 of Story Mode in Super Monkey Ball 2 and Super Monkey Ball Deluxe, and the 81st stage of Ultimate without continues (61st with continues).
This level is made of a backwards, S-shaped path with rectangles on the ends. It is tilted out toward the edge on the curves and diluted right on the center portion. The two rectangles are flat.
There is only a blue goal in this level. This goal is considered very easy. Go forward, and turn once you reach the start of the S. Turn left. Follow the path, making sure you remember to move your monkey properly. When you reach the end, turn right, and head into the goal.
