Pokemon GO Adventure Week 2025: Exploring the shiny odds of every spotlighted Pocket Monster

Pokemon GO Adventure Week 2025 shiny odds will be of interest to trainers taking part in this event. It started at 10 am local time on Tuesday, July 29, 2025, and end at 8 pm local time on Sunday, August 3, 2025. The event marks the release of Shiny Wiglett in Pokemon GO. While Toedscool and Toedscruel will also debut during the event, they will remain shiny locked.

This article covers all the shiny Pocket Monsters available during Pokemon GO Adventure Week 2025 and their shiny odds.

Note: The shiny rates mentioned in this article are all estimations based on the average shiny rate of Pocket Monsters based on their appearance patterns in the game. Therefore, a shiny rate of 1/512 doesn't mean that you are guaranteed one shiny for every 512 encounters you have with that critter.
