The Pokémon Pokopia game introduced a Halloween-themed event on October 17, 2026, allowing players to encounter Pumpkaboo and Gourgeist in special habitats. The event runs until November 1, 2026, based on the player's local time. Participants must have rebuilt at least one Pokémon Center to access the event. To earn event currency, players need to learn the Camouflage ability from Zorua during the Bleak Beach questline.
During the event, players can interact with Pumpkaboo at a rebuilt Pokémon Center. After a brief conversation, Pumpkaboo offers items in exchange for pumpkin candies. Players can also attract Gourgeist by creating one of two new event habitats. Event items are available for purchase from Pumpkaboo or can be replicated using a 3D printer.
To obtain pumpkin candies, players must trick other Pokémon using Camouflage. This involves disguising Ditto as specific items favored by target Pokémon. For example, a punching bag disguise can scare Hitmonchan, while a mushroom streetlight may work on Pokémon preferring bright habitats. Each Pokémon can only be startled once. When a Pokémon reacts to the disguise, removing the transformation triggers the scare, yielding one to three pumpkin candies per encounter. The exact reward distribution appears random.
The event adds nine furnishings, including a candy bucket, ghost smoke projector, pumpkin lantern, and Trevenant streetlight. Collecting all items grants a 'Trick or Treat' photo frame. Purchasing one of each item requires 20 pumpkin candies, potentially necessitating interactions with seven to 20 Pokémon due to variable candy drops.
Two new habitats are available: 'Give me something good to eat' for Pumpkaboo, requiring a table, ghost smoke projector, and candy bucket; and 'Creepy pumpkins' for Gourgeist, requiring a Trevenant streetlight, pumpkin lantern tower, and pumpkin lantern. Habitat details and requirements are only visible after constructing them once.
The event coincides with broader Pokopia guides covering island customization, Pokédex navigation, and early-game tips. Multiplayer features have restrictions in both standard and GameShare versions.
