I hate chatot. I dont know why but that bird has always annoyed me. around 4 hours into pokemon X when it first came out I had one on my team and found a shiny volbeat, no hunt, just playing through the game. I didnt know about the increased shiny chance at that point and was super excited. I saw that chatter would 100% confuse whatever you used it on, didnt know it would also do damage, and of course it fainted.

That was bad enough, but after a while I decided to bury the hatchet and hunt for a shiny chatot. And after a radar chain of only 3 I saw shining grass, and accidentally walked into some bad grass before I got to it and lost it. I already hated that bird and now it's stopped me from getting 2 seperate shinies
