The Petnis Forest is on the east of the island. From the Petnis Forest you can walk west to the Meadows Park.
At the moment there is only one place you can visit at the Petnis Forest: the Petnis Shack.
The Petnis Shack is located in a tree house which may be accessed by using the stairs on the right. Inside you can buy a Petnis if you are a premium user for $3,000 and you can choose its color and name. You can return after your initial purchase to exchange your current Petnis for another for $500.
For $300 the shop owner Marissa will also give you a demonstration of how Petnisses can be used.
