It ' s not a rule , but it ' s the current pattern . Why would it be stupid ? Zubat Golbat and Horsea Seadra both cost 50 Candies now which follows the current pattern of 2 stage , nonbranched families costing 50 to evolve . Most 3 stage families with the exception of the common ones cost 25 Candies to get from stage 1 to stage 2 , and 100 Candies from stage 2 to stage 3 . I don ' t see why that wouldn ' t be applied to Zubat and Horsea once Gen 2 is out . <| sep |> What is more disrespectful is asking people for help and completely disregarding what they ' re telling you . You ' re wanting an answer that you ' re not going to find except the ones that other people have given you <| sep |> That ' s a nice shot ! Much better than I thought possible from a Pony !
