Giant Comb is the 22nd stage of Advanced Mode in Super Monkey Ball 2 (61st in Super Monkey Ball Deluxe), the 2nd stage of Inside a Whale in Story Mode (19th in Super Monkey Ball Deluxe), and the 121st stage of Ultimate Mode without continues (101st with continues).
This stage is set up on a long platform with a comb spinning on it. The parts between the lines are safe points. The lines are where the teeth of the comb cross the floor. Getting in the way of one of these will send your monkey flying off the stage.
To get to the goal, use the stop and go technique. Wait until the comb spins. Then, move past the line, stop, and then repeat this again. Repeat the stop and go technique until you reach the goal.
