Pokemon Go players can catch Celebi starting August 20, Niantic announced today.

To catch Celebi, players must complete a series of special quests similar to spring's Mew quests. Celebi's quest line unlocks after completing the third of the seven Mew quests.

In celebration, Johto Pokemon will appear more frequently and HeartGold and SoulSilver clothing will be added to the store. A free Celebi t-shirt is available to all players.

Players who completed the Celebi quests during the Pokemon Go Fest in Chicago will get extra Celebi candy instead of a second Celebi. Smeargle is the only Gen 2 Pokemon not yet in the game.
