The next Pokémon Go Community Day in July will feature the Hoenn water starter, Mudkip.
The Community Day will take place on July 21 from 4-7 p.m. local time. Note that this is an hour later than usual. During this time, Mudkip spawn rates will be increased and there’ll be a high chance to nab a Shiny Mudkip for the first time in the game.
Mudkip is the final starter from the Hoenn region to get its own Community Day, but the wait will be well worth it. If Mudkip learns Hydro Cannon, it will be the second best water attacker in the game, right below Kyogre. (The likelihood of the Pokémon getting Hydro Cannon as its Community Day move is extremely high, as its other starter brethren got their respective special moves on their days.)
The Community Day will feature its usual bonus of 3-hour lures, but will also have another bonus of tripled catch XP. That being said, players should consider popping Lucky Eggs before running out to catch any Pokémon.
