The Gamepass Premium Plots allows a player to place their house on any glowing plot of land on Adoption Island. There are four of these plots in the main map; one being next to the hospital, two on opposing sides of the Grocery Store and one in between the Potion Shop and the Pool Party area.
The main use of this Gamepass is to place one's house on Adoption Island. This enables the player to be able to complete tasks more easily e.g. showering their pets or Baby without going all the way back to the neighborhood.
