First, go ahead and read my NMS guide but forget about Rice Beach 1, Stove Canyon 2 and 4, SS Teacup 3, Parsley Woods 1, and the entirety of Mt. Teacup. Before I tell you how to skip these, I should mention that every time you want to go back to a level that is after a level you skipped, you have to do the glitch again. Also this is pretty important: Usually if you complete a level without the Jet Hat in Stove Canyon, your best option is to go back to Mt. Teapot. However, since you skipped Mt. Teapot, you can’t go back there. So with the exception of the Reset rule on Stove Canyon 3 and 5 (Boss stage), whenever you get hit, reset. Here's how you skip these levels.

Rice Beach 1: Press down-right at the same time Wario stops on the level marker. You can get used to the timing after a bit.

Mt. Teapot: Once you leave the Mt. Teapot map press down-right and Wario will walk down to Stove Canyon. No, really.

Stove Canyon 2: Press up-right on the level marker with the same timing as RB 1.

Stove Canyon 4: Do the same thing as Stove Canyon 2.

SS Teacup 3: Do the same thing as the Stove Canyon levels.

Parsley Woods 1: Press down-right with the same timing on the level marker as the previous levels.

And that's it! If you're on a computer, here’s the link address to Greenalink’s video on these glitches. (I say if you’re on a computer because you can’t see the annotations he put up on anything else.)
