Shiny Unown

Last week during an in game events in pokemon go, you had the chance to catch unowns during raids. I’ve only got to see one that I took part of, and I got to the raid soon before it ended so I lucked out there. The letter for this one I got was ‘R’ which is one I didn’t have yet but that’s not the part I was happiest about. It’s that it’s a shiny.
