Is the Shadow Cacnea removed from Goldenwood Forest? After defeated the grunt with the Cacnea, he exclaimed "At least I still have Cacnea with me! Which implies that the Cacnea's supposed to be Shadow, but when I face it, it's not. I kinda need it for my Mono-Dark run.
Edit: Switched to Intense mode and it became Shadow! So apparently, Cacnea's only Shadow on Intense Mode.
