[Swablu]

Im trying to have 100 people visit my town to get the upgrade
BUT. I dont know how many people already came from the start.

Anyone know a way to find out?​

You sit on the tree in your town plaza. c:

Note that you can sit on the ledge of the tree after playing for fifty days, and a total of fifty hours over those days.

(Just in case your tree hasn't gotten to that point yet.)
