Wave Master is a very long path made up of thin, moving rectangles. Your monkey will start at one platform at the beginning of the path, and the goal will wait for you at the end of the path. Try to go as fast as possible on this stage because it is a very long pathway to the goal.
To get to the goal, go really fast on each fast moving platform. Don't go too fast while doing this because you'll fall off the floor right away. The best way to get through all these moving platforms is to have perfect timing. When you get to the end, just go straight into the goal.
