Poltchageist and its evolved form, Sinistcha, are making their debut during the Pokemon GO Halloween 2025 Part I event that will run from October 21, 2025, at 10 am until October 27, 2025, at 10 am local time.

During the event, Poltchageist will only be available in One-Star Raids. For now, Poltchageist’s and Sinistcha’s shiny variants will not be available in the game.

Players can evolve Poltchageist into Sinistcha using 50 Poltchageist Candy, adding another hauntingly adorable pair to their Pokedex.

Tips to maximize catching Poltchageist during Pokemon GO Halloween 2025 Part I

1) Focus on One-Star Raids: Most players, including solo trainers, will be able to encounter Poltchageist because it will spawn in low-difficulty One-Star Raids. Keep an eye on nearby gyms and use Raid Passes or Remote Raid Passes to participate in as many battles as you can.

2) Use Pinap Berries for extra Candy: Stock up early because it will take 50 Poltchageist Candy to evolve it into Sinistcha. To double your Candy rewards, always use Pinap Berries (or Silver Pinaps, if available) before catching Poltchageist. For even more value, take advantage of the event's 2x Catch Candy bonus.

3) Use Weather boosts to your advantage: Being a Ghost- and Grass-type Pokemon, Poltchageist is boosted in the Foggy and Sunny weather. When these conditions, it will appear at a higher level, making it stronger and worth more Stardust when caught.

4) Don’t forget the Transfer Bonus: During the event’s Tier 3 bonus, you will earn 2x (or 3x for GO Pass Deluxe) Candy for transferring Pokemon. After catching plenty of Poltchageist, transfer lower-IV ones to Professor Willow to quickly pile up more Candy.
