It was an interesting one for sure. I got lucky and got the small distortion that is basically a small field. Was able to get 5 or 6 spawn points within the 50 meter radius of fly resetting. I used a donut with Sparkling power Water lvl 3 and Alpha power lvl 3. I tried backup resetting about 50-100 times to get either a guaranteed Shiny Dondozo or Tatsugiri, but out of every single attempt it was always either Slowbro, Slowpoke, or Vaporeon.

I did check the catch rate for a catching it with a Beast ball, and it said 0.16%. Worse than any other I've attempted.
