A complete guide to Pokemon Go’s Ghoulish Pals event featuring debut Pokemon, new mechanics, and essential trainer strategies
Event Overview and Schedule
Pokemon Go’s Ghoulish Pals event represents the second chapter of the Halloween Mischief celebration, delivering fresh content for trainers seeking spooky encounters. This limited-time experience introduces two brand-new Pokemon species alongside innovative gameplay mechanics that will test your collection skills.
The Halloween Mischief event unfolds across two distinct phases: Creepy Companions followed by Ghoulish Pals. This sequential structure allows Niantic to build anticipation while gradually revealing content throughout October. Ghoulish Pals specifically enhances the spooky atmosphere by spotlighting Darkrai in five-star raids while introducing several collection-focused activities. Strategic trainers should prioritize their time during this event to maximize rewards. 
Pokemon Go’s Ghoulish Pals commenced on October 22, 2021, at 10 AM according to your device’s local time settings. This timing strategy ensures global fairness while accounting for regional timezone differences. Many trainers make the mistake of assuming event start times follow a universal clock, but local timing means you can begin precisely at 10 AM regardless of your geographical location.
The Ghoulish Pals event concludes on October 31, 2021, at 8 AM local time, officially closing the Halloween Mischief event series. This end time creates a strategic window where you can complete final tasks before the event disappears. Advanced players recommend setting reminders for 7:30 AM on October 31st to wrap up any unfinished Collection Challenges or Field Research tasks.
Special Research and Story Progression
The Misunderstood Mischief Special Research narrative continues directly from Creepy Companions tasks, maintaining continuity within the Season of Mischief storyline. This ongoing investigation provides context for the new Pokemon introductions while offering substantial rewards for completion-focused trainers.
Professor Willow’s narrative arc takes an unexpected turn following his “eye-opening” interaction with Phantump and Trevenant. This story development not only explains the sudden appearance of these ghost-type Pokemon but also hints at potential future narrative directions. Savvy trainers pay close attention to these story beats, as they often foreshadow upcoming events or Pokemon releases.
Niantic / The Pokemon Company
Pikachu, Piplup, and Driflim showcase special Halloween costumes available only during this event. Creepy Companions established spooky-themed Field Research rewards, and Ghoulish Pals expands this tradition with new tasks and encounters. These limited-time Field Research objectives become available between October 22, 2021, at 10 AM and October 31, 2021, at 8 PM local time. Experienced trainers recommend stacking similar Field Research tasks to maximize efficiency—for example, completing multiple “catch ghost-type Pokemon” tasks simultaneously yields better reward pacing.
New Pokemon Debuts and Collection Mechanics
Following Galarian Slowking’s introduction during Creepy Companions, Ghoulish Pals delivers two additional Pokemon families: Pumpkaboo with its evolution Gourgeist, and Phantump with its evolution Trevenant. These ghost-type additions significantly expand the available Pokemon roster while introducing unique gameplay elements.
As debut appearances for both Pokemon species, neither Pumpkaboo nor Phantump will feature shiny variants during this initial event. This follows Niantic’s standard release pattern where shiny forms typically arrive during subsequent events or community days. Collectors should focus on obtaining high-IV specimens rather than hunting shinies during Ghoulish Pals.
Niantic
The innovative size mechanic visually distinguishes Pokemon variants on the overworld map. Ghoulish Pals introduces a revolutionary new size mechanic coinciding with Pumpkaboo’s debut. This feature, currently exclusive to Pumpkaboo and Gourgeist, displays Pokemon in four distinct size categories: Small, Average, Large, and Super Size. This visual differentiation isn’t merely cosmetic—it affects collection requirements and creates new strategic considerations. Gourgeist inherits this size variation from its pre-evolution, making size hunting relevant throughout the evolutionary line.

Pumpkaboo Collection Challenge Strategy
Niantic
Successfully completing Collection Challenges contributes to your Elite Collector medal progression. Located within the Today View section, the Pumpkaboo Collection Challenge offers 5 Rare Candy upon completion while advancing your Elite Collector medal. To claim these valuable rewards, trainers must capture all four size variants of Pumpkaboo. Strategic planning significantly improves completion rates—prioritize common variants first while allocating specific time blocks for hunting rare sizes.
For comprehensive Collection Challenge details, including optimal evolution strategies for Pumpkaboo into Gourgeist, consult our specialized guide. Pro trainers recommend tracking your progress daily and focusing on the rarest sizes first, as common variants will naturally accumulate through regular gameplay.
Raid Schedule and Egg Updates
A dedicated Special Raid Weekend activates from Saturday, October 30,, 2021, at 10 AM local time through Sunday, October 31, 2021, until 8 PM local time. This concentrated raid period provides optimal opportunities for capturing featured legendary and mega Pokemon. Coordinate with local raid groups during this window to maximize premier ball rewards and catch chances.
Celebrating Mega Absol’s raid introduction, both this mega Pokemon and Darkrai will appear with increased frequency in five-star raids throughout the event weekend. This focused appearance rate allows strategic trainers to farm candy and pursue perfect IV specimens efficiently. Premium raid pass usage during this period yields maximum value compared to standard raid distributions.
Expanding the Season of Mischief Egg pool, Ghoulish Pals introduces spooky Pokemon exclusively obtainable from 7km Eggs. These event-limited hatches provide enhanced shiny opportunities while diversifying team options. Incubator management becomes crucial—prioritize 7km Eggs during the event duration to maximize special hatch chances.
