How about a category where you just complete every boss ( including all multi and single moon bosses). Timer starts on select and ends on when you finish bowser in the moon kingdom

this is just all missions OpieOP

what about all rematches in mushroom kingdom

Thats already been suggested

well in no other category is ther madam broodal in moon cave from what i know (i might be wrong)

Please don't make a category based on a madame broodal fight please please please please ok thank you

This is basically a slightly longer World Peace or All Story Moons.
