This speedrun could mean 3 things 1. Going to yoshis island (basically star%), 2. Capturing yoshi. and 3. Getting every moon that has Yoshi required (dark side included)

so the last one could be but make it you start with a post game file.

1st one is literally just star% 2nd and 3rd are just any% but you do something in mushroom

@Alexithink I think they mean dark included

@OloCube oop i didn't read all the way

still, that's just dark side but with all the yoshi moons

@Alexithink yeah I think it could only work if you start with a post game file

and even if that its iffy
