Here is what Niantic told us:
- Earn double the amount of Candy every time you catch, hatch and transfer Pokémon
- Don’t forget your Buddy Pokémon, because they will help you earn Candy four times as fast.
So now as the event has started and most of you would have already caught many Ghost Pokemon already. What we noticed is that “Niantic has mostly switched Water Pokemon Spawn points to Halloween event Pokemon spawn points“.
Now go out and find those points and make use of this event and catch as many Pokemon as possible.
