I was hoping to find a shiny Krabby or Wailmer during the event but then they released shiny Clamperl which meant I couldn't shiny hunt wild spawns much since we were driving around looking for stops so no shiny Krabby or Wailmer.
The first shiny Clamperl took 36 research, over triple what Feebas took.
I did get one wild shiny, my 8th Wingull.... Got 4 shiny Clamperl in 48 quests which was unlucky. But I get get both evolutions in 2 evolutions.
I'm hoping for a weeklong water festival so I can actually hunt for a shiny Krabby
