so basically you have to get to yoshi as fast as you can timing starts when the console starts up and ends the first frame the text box appears

So 120 Star?

no you would probably have to have a 120 star save file before hand tho

you can get in top of castle from a border before the cannon gets unlocked so the best way to implement the idea would be that if is posible, from a new file without the cannon unlocked idk if yoshi spawns tho

maybe but yoshi only spawns at 120 stars so that probably wont work (or i could be completely wrong tho)

Yeah getting to the castle roof early is possible (and very easy for that matter if you know what you're doing) but Yoshi still doesn't spawn until you have 120 stars.

yep
