From tomorrow, players will receive double the usual amount of candy for every Pokemon they catch.
And, as an extra bonus, the Professor will give two candies instead of one for every Pokemon transferred to him.
Hatching eggs will also yield extra candy - so your virtual trick-or-treat bag will be overflowing.
Some spooky Pokemon will be a lot more common as Halloween approaches, and gamers will see more of Zubat, Golbat, Gastly, Haunter, Gengar, Drowzee and Hypno.
