Pro Skaters is the 21st stage of Advanced Mode in Super Monkey Ball 2 (49th in Super Monkey Ball Deluxe), the 1st stage of Inside A Whale in Story Mode, and the 109th stage of Ultimate Mode without continues (89th with continues).
This stage features two goals that skate back and forth on a half-pipe. They slide off into the air, spin, and come back down. There is a play button and a pause button. The pause button only pauses the blue goal.
To get to this goal, roll on the pause switch when the goal is at the ground. From here, go straight into the goal.
This goal is considered very hard. A split second after the monkey first lands on the stage, hold up on the control stick; adjust right or left slightly if you are too early or too late. With this strategy, you should make it into the goal. Also, unlike the blue goal, the green goal won't freeze in place when the pause switch is pressed, so be careful.
