quite straightforward, just beat yoshi's house by doing a glitched exit; presumably just getting a magic orb in your reserve and using it.

What happens when you do that I don't even know

iirc nothing, just 1 unintended exit gets added

Ah so a 97th exit

We already have a category that includes that Yoshi House Exit it's called A2 Exit, though it's not beginner friendly. You collect the 96 intended plus those glitched exits. After the 99th exit it rolls to hex A0, A1 and A2 hence "A2" Exit.

I think what he means is timing ends when you hit the orb in yoshi's house

Also the orb glitch is there a easy way to do it I can't figure out how to do it

ohh i hadn't seen anything of that category, thanks

as for the orb glitch, there are a bunch of tutorials you can find on youtube and stuff but there is a guide on src.
