Cassiopeia is the 38th Expert floor in Monkey Ball and Super Monkey Ball, and the 67th Expert stage in Super Monkey Ball Deluxe. It also appears as the 177th Ultimate stage with continues, and the 217th without.
This stage consists of four rotating parallelogram platforms which continuously connect and break apart on a cycle. The start is on a small static platform and the goal is located on the last rotating platform.
This floor is hard, mainly at the end, where there is little room for rolling into the goal. Have caution, and take your time with the goal.
