Goal was to fully clear 1 child dungeon and 1 adult dungeon, so all chests, gold skulls, boss, heart container, stone/medallion, along with visiting every room and opening every key-locked door, then after all of that for each dungeon pausing and showing that the map is filled out. If you look up "ootmasterseries" and go to task 5 on the website you'll be able to see the full details.
