Instructions
Use your kart̵7;s hop function to cut the 90-degree ice corners in Sherbet Land. You risk falling in the water, but successfully leaping over the corners can shave seconds off your lap time.
Head to the right around the massive ice boulder just before Sherbet Land̵7;s tunnel entrance to find a hidden boost ramp and some power-up cubes.
Keep a watchful eye for incoming mortar shells in Shy Guy Beach. They have a large explosion radius, and being smacked by one can deflate your hopes of a first place finish.
Skip the grassy field near the finish line of Shy Guy Beach by sticking to the sandy strip of beach on the left.
Watch for shortcut opportunities in Delfino Square. There is a boost-only jump to the left as you exit the main town and a hidden alley just a bit further up the track to the right. You can also boost over the grass on the course instead of turning around it.
Hit each boost ramp in Waluigi Stadium as close to center as possible. This gives you the highest chance of hitting a power-up cube in the air.
Perform jump stunts (by shaking the Wiimote) off every hump in the course. This keeps you boosted for the majority of the race.
