Shiny Pokémon in Pokopia?

Ever since the game has been announced, I have been thinking about how shiny Pokemon might be included. From what was shown, I am not entirely sure how shiny Pokemon could be included in this game, but I have feeling that they are somehow. It would certainly be a nice addition to this game if shiny Pokemon could roam around your base. What do y’all think? Could shiny Pokémon be included and how? Let me know.
