Niantic announced that Pokémon GO’s June Community Day will be on June 16, 2018 and featured Larvitar.
Same as before, it will keep 3 hours Lure Modules. In additional, it will be 3x Exp. So, Trainer remember to use Lucky Egg to boost up your exp.
Niantic did not announced for the Shiny Larvitar and exclusive move, so let’s wait Niantic for further announcement.
