I'm trying to find Aqua Tauros in Violet. Everything I can find online seems to indicate it just shows up in the middle of normal packs of Paldean Tauros, but I've checked a bunch of those packs and can't find it. Is this just extremely bad luck(I've seen well over 10 packs), does the different appearance not show up in the overworld, or does something have to trigger for it to appear?
