Shiny Shuppet

luck of the draw, my first shiny (and currently only...) was shuppet a couple of days after halloween event ended.

keep trying, they are still out there.

I think you just haven't had good luck, because I highly doubt they would remove shiny versions that were already available. I can't prove that from my own experience, though, since I've never caught a shiny anything, and I also haven't seen a single Shuppet since Halloween.

By far the rarest shiny out there. I still don't know anyone in my area fortunate enough to catch one

They should still be around. I've caught probably at least 1000 shuppets during the event and no shiny. But I've also caught a shiny Pikachu from a nest and it was 1 month after the event that launched that Pikachu.

I am not sure which timeframe "still" refers to, after Halloween or after Christmas. In any case, I got my Shiny Shuppet on the morning of 25th December. I would all him a Christmas gift, only giftgiving happens on the evening of 24th here in Germany
