At Pokemon Go Fest in Chicago today, attendees were given the chance to catch Celebi via the game’s Special Research during a Pokemon Go Fest-specific quest line.
The five-part quest led players across the event’s 1.8-mile walking course in Chicago’s Lincoln Park. The quest included tasks ranging from catching various types of Pokemon to finding the elusive Unown.
Unown (which can take the form of 26 different letters or two punctuation marks) spawning in Lincoln Park during the event spelled out “CELEBI?,” which marks the introduction of the question mark variant in Pokemon Go.
Niantic hinted that Celebi was coming last week, nearly completing generation 2 in Pokemon Go with the exception of Smeargle, who is now the sole Johto Pokemon who has not yet appeared in-game.
