Idk, if there's thread with similar discussion, but I just experienced one of those moments described in the title.
I was hunting a shiny Fomantis in Lush Jungle, using the standard False Swiping method (with Scizor), when I have two males Lv. 18 and both of them used Growth. The message usually reads, that both Attack and Special Attack grew, but, the hell, by both Fomantis, the text was different, and such both Attacks and Special Attacks FELL. I was like: “What's going on? Attack and special attack should grow, right?” I changed to my Smeargle with Transform and Transformed into one of those Fomantis, didn't knowing Fomantis's Hidden Ability, and to my surprise, it had Contrary! Changed back to Scizor, then back to Smeargle and transformed into the other one. And it has Contrary, too! Unfortunately neither of them was shiny, but I just had to catch that one, so I killed one of those and catchede the other, but… OK, what's the chance to get TWO Hidden Abilities in a row? I had to be very lucky, right? OK, similar chance is to get two shinies in a row… and getting two shiny hidden abilities must be almost impossible, but still… two Contrary Fomantis in a row, I just had to share that moment. Well, good luck to y'all. ;-)
