Unlike most Evolution Items in Pokémon Scarlet & Violet, the Moon Stone only is related to a single pocket monster’s evolution instead of two. As a result, the game only features one guaranteed method of obtaining this stone. If players wish to get another, they will need to deal with the RNG mechanics of foraging or the Auction House. These are not bad by any means but will undoubtedly hinder the rate at which Moon Stones can be acquired. Fortunately, the related pocket monster for this Evolution Item is well-known for its adorable appearance but not popular in combat. Therefore, evolving once should be sufficient unless Trainers encounter its Shiny.

Starting from the Pokémon Center of Area Three, players must head slightly northeast, following the elevated trail until reaching a spacious gully with two patches of grass with trees. Glide downward to the patch in the corner with the smaller tree, and a glowing Poké Ball should render into the players’ view. After landing, pick up the item to obtain a Moon Stone.
