Wandering Pokémon

Wandering Pokémon are special Pokémon that sometimes appear in certain areas of Rota. These cannot be caught but can pass Egg Moves to other Pokémon in the area (for example, a wandering Xatu may cause Woobat in Lynwood Cliff to know Stored Power). This is more likely to cause those Egg Moves than standard mutations, but chain breeding is possible (although it's less likely). Wandering Pokémon can be identified and interacted with at the top of each area, and multiple Wandering Pokémon at once in the same area may lead to chain-bred moves (for example, Vulpix with Freeze-Dry getting the move from a Lapras and a Delibird).
