The Gamepass Premium Plots in Adopt Me! 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 next to the Hospital, two on opposing sides of the Supermarket, one in between the Potion Shop, and the Pool Party area. It costs 499, making it very expensive for most players.
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 easier. An example is being able to shower their pets or baby without going all the way back to the Neighborhood.
