Fly to your favorite Wild Area, and it will automatically perform shiny hunting when you plug the USB into the Switch dock. Sometimes there is a slight misalignment when the Battle Zone appears, so if it doesn't work properly, please re-insert the USB. I can also sell a microcontroller for Froakie shiny hunting, so please feel free to ask. ⚠️Shiny hunting is not possible if enemies immediately attack after entering the Wild Area.⚠️ Please comment before purchasing. Please comment if you have any questions. ※There are similar products, but this one operates with a unique code.
