On Thursday, August 15th, PokemonGoApp tweeted an image of a starry sky with the Pokemon GO logo and five star emoji.
Since then and every 24 hours, PokemonGOApp tweeted the same image, with one less star emoji every day and also, more stars inside the image of the tweet.
On August 18th, the tweet showing 2 emoji stars and the stars inside the image forming Jirachi!
It’s reasonable to expect at least some further information on Jirachi when the countdown is over on August 20, 2019, at 3 PM CST.
Stay tuned for further details.
