In Abandoned Discovery island by @FateForWindows

there was a ending that sparked well... alot of drama

it was the true ending as a joke but no one liked it

so what you have to do is go to the caverns get a key open the chest and get the other key and then beat all the nights by befriending the suits and after escaping from pnm on night fives cutscene

you have to fight true mickey then a undertale boss battle

alot of people disliked it although i liked it in my opinion

but now you know...
