Now that the festival's almost over, Oaty's probably feeling the burn of all that paper in him. So, along with the worries, maybe Oaty could turn into a quest? Could be kinda like Major Drills, but it involves stuff that would benefit Oaty. Feed him with X amount of food items, pet him so many times, read him certain books, groom him with grooming items, etc. Prize could be sP and Oaty/farm-related items. I'm not saying get rid of the worry part just adding to it
