Start at the pier (Where Tetra's ship is), go past the houses and to the bridge, either cross the bridge (straight path with coins) or go through the water (Some hazards and item boxes), Drive past more houses (Hazard: Giant Black pig is sometimes in the road), drive up the hill leading to the bridge (possible Anti-grav section), either cross the bridge or drive up one of the rocks and take the glider across (Homage to using deku leaf to glide to the forest when the bridge is out)[item boxes for bridge, coins for glider segment], weave through the forest (some sharp turns), drive into a hole in the ground through the great fairy's fountain (Sometimes she throws coins onto the track)[reference to how the Outset great fairy was the one who upgraded the wallet], drive into a cave section inside outset island, then come out on the alcove where the big stone head is. enter a big hole into a straight downward anti-grav vertical section that passes through the floors of the savage labyrinth (Hazards: chu-chus stuck to the walls, flame pillars that come from columns), go back into regular gravity and come out of the side of the cliff and into the water outside of Outset (Below the pot that has 100 rupees in it), drive through the water and come out on the beach near the three boats, drive past Grandma's house (Where she and Aryll will be waving to you) and straight to the pier.
Bonuses: Have the mailman standing by a bouncing mailbox, have many seagulls perched on Arylls lookout, and put a Big Octo in the distance. Don't forget the Snot Kid. Put the telescope guy up by the bridge, and have him look at the big octo.
How does that sound for an Outset Island MK8 Course?
