Spinning Saw is the 43rd Expert stage in Challenge Mode and World 9-3 in Story Mode.
A large circular saw spins counterclockwise and hovers up and down through a hole in a doughnut-shaped platform. The goal is in the middle of the saw. There are 3 banana bunches and 3 single bananas near the edge of the saw.
There is only one goal, the blue goal. Hold up on the control stick and land on the saw when it is lower than the doughnut platform. Stay near the middle to avoid falling off the side of the saw, and head into the goal.
