Which new shinies debut in Halloween Part 1 and their spawn rates
The new shiny Pokémon debuting in Pokémon GO Halloween 2025 Part 1 are Shiny Sinistea and Shiny Polteageist. Shiny Sinistea, in particular, has increased spawn rates during the event, both in the wild and in raids, making it a prime shiny hunting target.
Most of the event’s wild spawns of Ghost and Dark-type Pokémon can be shiny except for Greavard and Hisuian Zorua, which do not have shiny forms available during the event. The event features boosted spawns for various Pokémon such as Zubat, Gastly, Spinarak, Sableye, Shuppet, Duskull, Drifloon, Purrloin, Venipede, Zorua, Hisuian Zorua, Vullaby, Greavard, and Sinistea. Among these, Sinistea and Poltchageist are newly introduced shinies.
Shiny Sinistea has a boosted shiny rate particularly in one-star raids (where Poltchageist also appears). Wild shiny Sinistea encounters are also boosted compared to usual shiny chances. The exact numeric spawn rates are not disclosed officially but are significantly higher for shiny Sinistea compared to most other Pokémon in the wild and raids during the event.
In summary:
-
New shiny debuts: Shiny Sinistea and Shiny Polteageist
-
Increased shiny chances for Sinistea in wild spawns and one-star raids
-
Most wild event Pokémon are shiny-eligible except Greavard and Hisuian Zorua
-

Where to find Shiny Sinistea most frequently during the event
During the Pokémon GO Halloween 2025 Part 1 event, Shiny Sinistea can most frequently be found near PokéStops and in green areas such as parks and gardens where spawns are naturally higher. Players report encountering about one Sinistea spawn every 5 to 6 PokéStops in typical gameplay, with even higher spawn densities during Spotlight Hours where lures and increased spawns boost numbers significantly.
Foggy weather increases spawn rates of Ghost-type Pokémon including Sinistea, enhancing the chances of finding a Shiny one. The event features boosted wild spawns of Sinistea, which is the best place to find shiny variants naturally in the wild.
Spotlight Hours and Mass Outbreaks (specific to game mechanics in Pokémon Scarlet and Violet references) also suggest concentrated rare spawns, although Pokémon GO mainly focuses on event spawns near frequent PokéStops and green areas.
To maximize shiny hunting for Sinistea in Pokémon GO during this event:
-
Hunt near clusters of PokéStops and green spaces like parks.
-
Play during foggy weather for ghost type boosts.
-
Participate in Spotlight Hours, which dramatically increase spawn density.
-
Use lures and incense to further increase spawns.
This approach gives the best chance to encounter and catch Shiny Sinistea frequently during the event.youtube+1
