Secret Course 01
From the Super Mario Wiki
Secret Course 01 is the first secret course that appears in the Remix 10 mode of Super Mario Run. This secret course takes place in the grassland.
This course is full of many Boos that the player must avoid. It starts off with a ? Block containing a Super Mushroom. The player must jump up to a second piece of ground, where the first Bonus Medal is found on the edge. The second Bonus Medal is found right after this in the air by jumping from the third piece of ground. After that is a lower fourth platform where the player must jump again to get the third Bonus Medal. There are then three higher pieces of ground where the fourth Bonus Medal is found next to the wall of the last high piece of ground. The fifth and final Bonus Medal is in the air right before the Goal Pole.
