How many Bidoof will you catch? When will it end? Read on for more details. Good luck—you’re going to need it.

Features

• Bidoof will be appearing more often in the wild, in raids, and in encounters after you complete event-exclusive Field Research! If you’re lucky, you might encounter a Shiny Bidoof! Our preliminary research suggests that the rate at which Bidoof will be appearing in the wild will increase over the course of the event.
• On certain days of the event, Bidoof you encounter will know attacks that they normally cannot learn. On Thursday, July 1, 2021, from 10:00 a.m. to 8:00 p.m. local time, you can use a Charged TM to teach Bidoof any of these attacks. After the event, you can use an Elite Charged TM to do the same. During each of the times listed below, you can encounter Bidoof that know the following attacks.
  • Shadow Ball: From Friday, June 25, 2021, at 10:00 a.m. to Saturday, June 26, 2021, at 11:59 p.m. local time
