For your convenience, all courses with a treasure are marked with a key icon (ripped from Yoshi for NES)! This route through the category assumes you will be doing course skips on the map screen (located in parenthesis on the appropriate segment), done by pressing two directional inputs (or a rightward diagonal) on the same frame.

NOTE: To save yourself a simple boss fight in Mt. Teapot, you skip doing course 12 its entirety after obtaining course 11's treasure. Warning, once you skip Mt. Teapot on the map and then enter a level, YOU CANNOT GO BACK!
