Superman mud gap jump
The Superman strat: drift out super wide onto the wall left of the metal line, charge an orange mini-turbo while dragging it, release and do a boosted left charge jump off the highest point of the ramp (through the coin) to fly over the entire mud patch. Requires the super mini-turbo boost still active - a blue mini-turbo will not make the distance.
Chocolate pool mushroom cuts
From the starter boost, quick right drift and hop over most of the mud for an effective turn skip; from a previous lap it needs a soft-drifted orange mini-turbo off the final ramp and a precise angle.
Left guardrail billboard ride to the finish
On the final turn before the last ramp section, get on the left guardrail and ride it to the end by left-flipping up onto a billboard, grinding the billboard and another rail before dropping to the goal.
