Second Floor Of Museum.

[CherryBlossomCrossing]

I've donated what seems like 20+ fossils, and 1 or more in other categories.
But yet, i still haven't seen Blathers thinking.
Help?

I think you need to donate a total of 50 items and I think there's a day requirement too. I remember on one of my resets it seemed to take forever to get the second floor.
