N64 Sherbet Land
GBA Shy Guy Beach
At the start you will hopefully notice that there is a ship and it fires mortars all over the place. However, these don't go off immediately and you will have some time to avoid them before they explode. When you get to all the mini islands, place bananas on them so that if the other racers try and cross the islands (and they will), then they will be slowed down.
DS Delfino Square
The exact same as the D.S. The only way you can do a mid air trick is on the drawbridge.
GCN Waluigi Stadium
This track has many half-pipes and boosts in it. At the start, you go over a bump with item boxes. Then, after a ramp, you can either safely take the half-pipe, or, with a kart/bike of good handling, can make the difficult turn. An opprotunity for a shortcut is using a mushroom to fly across the mud. Then you go to a large areawith metal piranhas, fireballs, and half-pipes. After another hard turn/half-pipe, you go across a ramp to the finish line. But if you fail the last jump, you will fall down and lakitu must come and rescue you. Pretty easy track with nice music.
