Update: Found this: https://twitter.com/Chrales/status/1048305133480828929
ditto shiny (finally) added server-side
pikachu + raichu with new hats (no pichu)
The official name of this form is “Fragment Hat Pikachu” or “F.H. Pikachu”.
I don’t think they are boosted shiny rates if that’s what you mean.
Yes, and there’s more!
Maybe another pikachu for halloween
