I just got a 1/18,432 Unown in Leaf Green Tanoby Ruins!!! Check out this beauty! It appeared after ONLY 4354 encounters so WAY under odds! It literally left me shaking, it's my rarest shiny, more than 2 times rarer than any of my regular 1/8192 shinies! Explanations in comments pic.twitter.com/Jh0MxXmiAQ
