Lap 1: The track starts off inside peach's castle, until you go to the hallway with bowser at the end. You will have to ride out the window like in-game. You go into glider mode and go through Star Boosters. Lap 2: You reach star haven and pass through it. You then go down the Star Way Spiral onto shooting star summit. Lap 3: You go down the summit and then go down the path to the crater where the castle was. You then barge though the huge blue gates into toad town, where you will find toads waving at you. You will turn right into a huge sideways pipe which will send you to the finish line right before Mario's House. (Luigi will wave at you.)
My submission for this contest by @WigglerWendsday : https://scratch.mit.edu/projects/1201202435/ I REALLY love Paper Mario, and I've always wanted a track for it.
