When someone reaches level 99 in all the townsfolk there should be a quest with the prize of a key the quest could be called key to the town that can be used to unlock a gold key shaped mailbox.
Would also be nice if at the bottom of the townsfolk page there was a list of names or link to a list of names of all the people who have all the townsfolk to level 99 it would give ppl a reason to get any new townsfolk to 99 in the future to stay on the list.
