Yes.
You need to get 5,000 Nook Points.
On some days in Animal Crossing Tom Nook will say he's having a sale where you get 5x the points you usually get
the most expensive things
Get a 'Makeover' at Shampoodle's in the city.
Because if you get a certain amount of points, there are rewards that Nook can give you.
You can't buy it, you have to have enough points in Tom Nook's point machine
You can get it in tom nooks store but not to buy with bells you get it with your points for about 11,000point's (you can get points buy buying things in his shop)
Fossils are under ground at random points in the day or night.
first get lots of bells (bets way is to hack) then pay it all and ta-da
It's random.
No. EDIT: In city folk you can, by getting points from tom nooks place (not sure how much though)
to be a member of redds shop you need an invitation from ether a animal or a friend. if you are talking about nooks shop you need to get 5,000 points to be silver member, 10,000 points to be a gold member, or 20,000 points to get platinum member.
