Niantic announced that Pokémon GO’s July Community Day schedule on July 8, 2018 and featured Squirtle.
Same as before, it will keep 3 hours Lure Modules. In additional, hatching distance only need 25%. So, Trainer remember to use Super Incubator.
Niantic did not announced for the Shiny Squirtle and exclusive move, so let’s wait Niantic for further announcement.
