So I needed a way to get the forest WW in a faster way. Luckily, in vorpal's wr, he showed me a faster way.

1st, Play through the WW run like normal up until you finish the warp zone. Then, instead of going to level 6, go straight to level 11. Once you make it to level 11, beat it the 1st time without getting the bandage, Then, replay it 3 more times but this time get the bandage. If done correctly, the glitched world will show up and you can finish the WW like normal.
