Story Event: Pasio Eggsplorers
The Pasio Eggsplorers story event will begin on April 1 at 11 p.m. PT. This story event is unique in that you’ll be able to acquire Eggs that hatch Pokémon. To coincide with the event, two sync pairs in seasonal attire will appear, so we hope you look forward to their reveal.
