2017 Halloween Event
As part of the 2017 Halloween Event, Pikachu in this area is replaced by a disguised Pokémon overnight. When encountered, it still appears as Pikachu at first, but it acts strangely and reveals that it is not Pikachu! This special Pokémon has a low catch rate and only appears at night, so bring Dusk Balls for catching it. The event lasts from 13th to 31st October, 2017.
Note: Rarity levels are estimations according to this scale and might be subject to changes due to different encounter assessment results, unless supported by official encounter rates, which are listed in red under the rarity level if known. If there are any Pokémon with low catch rates, the possibility to flee or requirement of gaining happiness to evolve, recommended Poké Balls for that Pokémon will be shown with the corresponding bag sprite under the Pokémon's name.
