A Ghost type event is coming to Pokemon go on Sunday, October 25, 2020, from 8:00 a.m. to 10:00 p.m. local time and Drifloon will be spawning more often during this time.
Drifloon is already released as a shiny, so there will be an increased chance of you being able to catch the shiny during the event.
There will be a time research task that will be available during the time event, and will need to be completed by 10pm in order to get all the rewards associated with it.
There will be Field Research tasks that you can complete that relate to this event and you will, for the first time, be able to get Mega Energy for Gengar.
The Bonus for the event will be extra XP for Nice, Great and Excellent throws. The exact multiplier for the XP reward is currently unknown.
As Mega Gengar is coming to Pokemon Go, it is possible that Gengar and possible Mega Gengar will appear in raids, but this has not been confirmed.
