Organic Form is the 11th Stage of Advanced in Super Monkey Ball 2 (29th in Super Monkey Ball Deluxe), the 1st stage of Under the Ocean in Story Mode in Super Monkey Ball 2 and Super Monkey Ball Deluxe, and the 89th stage of Ultimate without continues (69th with continues).
This stage features a large platform that changes formations constantly, hence the name. It changes formations by weaving back and forth and at different angles. There is a play button and a fast-forward button. The goal is located on a small, rectangular platform adjoined to the large weaving platform.
To get to the goal, it is recommended to activate the play button as it is bit easier to beat the stage with it activated. From here, roll onto the large weaving platform. Try to stay as much in the center of the platform as possible. Slow down if you are off-course or if you are accidentally going too fast. Repeat this pattern until you make it to the goal.
