Complete guide to Pokemon Go’s Creepy Companions event with dates, rewards, and expert strategies
Introduction: Halloween Mischief Event Overview
Pokémon Go’s Creepy Companions kicks off the Halloween Mischief celebration with an impressive array of spooky features designed to delight trainers. This first installment of the seasonal event delivers much-anticipated content including exclusive costume Pokémon, the long-awaited Galarian Slowking debut, refreshed egg pools, and special research opportunities.
The Creepy Companions segment of Pokémon Go’s Halloween Mischief event delivers an exciting start to the spooky season with fresh costumes, ongoing Season of Mischief Special Research progression, Galarian Slowking’s arrival, and multiple collection opportunities.
Niantic’s popular mobile game continues its tradition of elaborate holiday celebrations, with Halloween receiving particularly extensive treatment. The developer has organized the festivities into two distinct parts within the broader Season of Mischief framework. Beyond the visual treats of costumed Pokémon, trainers can anticipate themed egg hatch pools, challenging raids, the definitive arrival of Galarian Slowking, and substantial research narrative progression. This comprehensive guide details everything required to maximize your Creepy Companions experience in Pokémon Go. 
Event Schedule and Timing
The Creepy Companions phase of Pokémon Go Halloween Mischief commences on October 15, 2021, at 10:00 AM according to your local timezone. This timing strategy ensures all players worldwide experience the event simultaneously relative to their location.
Creepy Companions concludes precisely one week later on October 22, 2021, at 10:00 AM local time. The subsequent segment, titled Ghoulish Pals, immediately follows this conclusion, maintaining continuous Halloween festivities throughout the remainder of October.
Pro Tip: Set calendar reminders for both start and end times to ensure you complete all time-limited research tasks. The local time scheduling means West Coast players actually gain three extra hours compared to East Coast participants when planning their final day activities.
Costume Pokemon and Shiny Hunting
Consistent with previous Halloween celebrations, Pokémon Go introduces special costumed variants for this event. Halloween Mischief Pikachu, Piplup, and Drifblim receive festive makeovers with spooky thematic elements. Critically, all three costumed Pokémon maintain their shiny potential, providing collectors with valuable hunting targets.
These costumed Pokémon can be acquired through multiple methods:
- Wild Encounters: Increased spawn rates for costumed Pokémon in their natural habitats
- Field Research: Complete specific tasks to encounter costumed variants
- Egg Hatches: Certain costumed Pokémon may appear in event eggs
Shiny Hunting Strategy: Focus on completing as many Field Research tasks as possible, as these encounters often provide better shiny odds than wild spawns. Use Incense during event hours to maximize costumed Pokémon appearances, and prioritize areas with high PokéStop density for more research opportunities.
Special Research and Field Tasks
The ongoing Season of Mischief Special Research narrative, Misunderstood Mischief, unlocks additional chapters synchronized with Creepy Companions. This story progression deepens the seasonal mystery while providing substantial rewards.
Trainers can now advance through Steps 8 and 9 of the narrative arc, earning Galarian Slowpoke-themed compensation for their efforts. Comprehensive walkthroughs for the complete Misunderstood Mischief Special Research storyline are available through dedicated guide resources.
Niantic / The Pokemon Company
Pokemon Go’s Halloween 2021 celebration delivers substantial research rewards. Field Research tasks during Creepy Companions provide encounters with a specially curated Pokémon selection:
Field Research Completion Tip: Focus on tasks that reward encounters with Pokémon that have shiny variants. Delete tasks that don’t offer valuable rewards to maximize your event productivity. Keep an eye out for tasks that reward rare candy or premium items, as these provide additional value beyond Pokémon encounters.
Galarian Slowking Debut
Galarian Slowking makes its Pokémon Go debut during Creepy Companions – a highly anticipated addition that completes the Galarian Slowpoke evolution line. This Psychic-type Pokémon becomes permanently available, not limited to the event duration.
To evolve Galarian Slowbro into this distinctive Water/Psychic-type variant, designate it as your Buddy Pokémon and successfully capture 30 Psychic-type Pokémon. This evolution method encourages strategic buddy selection and type-specific catching.
Evolution Optimization: Visit areas with high Psychic-type spawns like parks or water biomes to accelerate the 30-catch requirement. Using Psychic-type lures or incense during windy weather (which boosts Psychic spawns) can dramatically reduce evolution time. Remember that certain Field Research tasks also reward Psychic-type encounters.
Battle Viability: Galarian Slowking performs adequately in Great League PvP battles thanks to its unique typing and movepool. While not meta-defining, it provides interesting coverage options against popular Fighting and Poison types.
Wild Encounters and Spawns
Creepy Companions significantly alters the wild spawn pool with appropriately spooky Pokémon selections. Part One features increased appearances for these thematic creatures:
- Halloween Mischief Pikachu (Shiny chance)
- Halloween Mischief Piplup (Shiny chance)
- Drowzee (Shiny chance)
- Gastly (Shiny chance)
- Spinarak (Shiny chance)
- Misdreavus (Shiny chance)
- Shuppet (Shiny chance)
- Woobat (Shiny chance)
- Yamask (Shiny chance)
Spawn Optimization: Use Incense during event hours to guarantee approximately one spawn per minute. Focus on areas with diverse biomes to encounter the full variety of event Pokémon. Nighttime hours may slightly increase ghost-type spawn rates, though this hasn’t been officially confirmed.
Common Mistake: Don’t waste Poké Balls on common spawns unless you’re specifically hunting candies. Prioritize costume Pokémon and rare spawns to conserve resources for when you encounter shinies or perfect IV specimens.
Raid Boss Lineup
Each new Pokémon Go event brings refreshed raid content, and Creepy Companions introduces a thematic boss roster that will have trainers coordinating battle groups.
Raid Tier Breakdown:
- 1-Star Raids: Typically feature costume Pokémon and common ghost types
- 3-Star Raids: Mid-difficulty bosses requiring small groups
- 5-Star Raids: Legendary encounters needing coordinated teams
- Mega Raids: Mega-evolved Pokémon providing temporary boosts
Raid Strategy: Coordinate with local communities to tackle higher-tier raids efficiently. Use remote raid passes to join battles outside your immediate area if local participation is limited. Focus on raids featuring Pokémon with shiny potential or meta-relevant battle capabilities.
Counter Preparation: Ghost-type raid bosses are weak to Dark and other Ghost-type moves. Prepare teams featuring Hydreigon, Giratina, Chandelure, or Tyranitar with Dark-type movesets. Fairy-types effectively counter Fighting-type bosses that may appear.
Egg Hatch Pool Updates
Complementing the Season of Mischief egg inventory, Creepy Companions introduces spooky Pokémon to 7km Eggs obtained during the event period:
- Spinarak (Shiny chance)
- Misdreavus (Shiny chance)
- Shuppet (Shiny chance)
Hatching Efficiency: Use a Super Incubator to reduce walking distance by 33%, allowing you to cycle through more eggs during the event. Focus on obtaining 7km eggs from gifts during the event period, as these contain the exclusive Halloween Pokémon.
Egg Management: Clear inventory space before the event starts to ensure you can collect maximum 7km eggs. Avoid opening gifts when your egg inventory is full, as this wastes potential event egg opportunities. Walk during the event with available incubators to hatch eggs quickly and make room for more.
