Super Mario World: Return to Dinosaur Land - World 7 (Bowserland)

Well this world's annoying.

First few courses can be a nightmare in terms of perfect execution, and they can be very unforgiving when the spaghetti happens. Bowserland 3 is especially tricky with the "Indiana Jones" first half and the forced auto-scroll lava section.

The strategy I've shown for Bowserland 4 at the info block showing that the Red Switch can be found is actually cheese. The intended strategy is to take the raft, hit a turn block that actually contains a vine, then get to the next row of turn blocks and jumping through. Now this is a "if you don't get it, you're dead" scenario, so the cape strategy that I use is a lot more forgiving, as the only way to die is by a timeout, but it's still pretty tricky to execute. A far safer strategy (that I don't show) is to spin jump on one of the blocks near the towering wall ahead of time before taking the raft and hitting the vine block.

The Switch Palace itself can be tricky if trying to get the moon, so it may take several tries to get it. The gas chamber at the Ghost House gives no time to dawdle without a cape. In direct contrast, Bowserland 5 is the easiest stage by far, even if some parts can be hard to see without the Disco Ball.

Bowserland 6 is by far my favorite course in the hack, but it requires precise execution (a theme for this world as I've hinted at) for a prolonged (if short) period of time. In order to land on the first Banzai Bill, make sure to hold right without holding B, then hold B as you're about to hit it until you land on the ground.

I also show the Secret Isle from Urchin Ocean to get a cape, which I recommend for Larry's Castle. The first room with the saws is tricky, but the rest of the castle is pretty easy. Unfortunately, I barely miss the cape at the boss fight, which I will say is necessary to have for the final stage...
