Instructions
Perform any random trick to begin a combo. A corkscrew is a good option and can be achieved by pressing the down arrow while airborne.
Hop continuously in the shallow water for approximately one minute. The first move plus the jumping will increase your speed.
Stay as horizontal as possible and tailslide by pressing the down arrow when approaching a wave. Jump off the wave from the tailslide and press the down arrow immediately and do not release it.
Jump off of any starslides you encounter and again press the down arrow and hold it. Once you reach Jupiter, do not jump off of the starslide and allow yourself to follow the stars into the water.
Do another tailslide as horizontally as possible when approaching the water. Jump and hold the down arrow again.
Catch all of the starslides on the way up. If you reach Neptune's starslide with enough time left, slide back down to the water and perform another tailslide and jump maneuver. Remember to hold the down arrow after you jump.
Catch the starslides, jumping off of them like before. After jumping from the starslide on Pluto, you should reach the restaurant.
