"How to tell if it's a ditto... Feed it a Razzberry!"

#PokemonGO: I hope this hasn't already been posted I searched a little and couldn't find anything. Over the last month I had suspected but wasn't able to confirm until recently, that when you feed a Pokemon a raspberry... if it is a ditto the animation behind it will be purple.I've been noticing that the animation looks differently for a while now but I finally put two and two together and having been paying attention recently. I've realized that Pokemon disguised as ditto will have purple light in the animation behind them when being fed a raspberry.Can other people confirm this please?Unfortunately I wasn't able to take a picture when I confirmed this but I will begin taking pictures from now on and hopefully I will get one to share.Here is a Non-Ditto Rattata being fed a Razzberry during the daytime. http://ift.tt/2oycAMg'll post a pic from a nighttime catch tonight and will post a Ditto catch pic asap!! via /r/TheSilphRoad http://ift.tt/2qgclli
