Pokémon Sleep Halloween 2026 Guide: Best Research Areas, Pokémon to Catch & Event Bonuses

Pokémon Sleep has officially announced Halloween 2026: Double Candy Research, taking place from October 26 to November 1, 2026.

As in previous years, the event will feature double or triple Candy rewards from sleep research, along with special bonuses for Ghost-type Pokémon.

Two new Pokémon, Misdreavus and Mismagius, will make their debut. A special Halloween Eevee wearing a purple hat will also appear.

In this guide, I’ll cover the Halloween 2026 event bonuses, which research area to choose, which Pokémon are worth catching, and how to prepare before the event begins.

Pokémon Sleep Halloween 2026: Event Dates and Details

The event will run for one week, just like previous Halloween events.

This year, the event will take place on Greengrass Isle and Greengrass Isle EX, so you’ll need to choose one of these two areas.

Halloween 2026 Event Bonuses

Halloween 2026 offers increased Candy rewards from sleep research and several bonuses for Ghost-type helper Pokémon.

Double and Triple Candy From Sleep Research

The Candy bonus applies only to the first sleep research session of each day.

This is a great opportunity to collect Candy for Pokémon that are normally difficult to raise.

October 31 and November 1 are especially valuable because Candy rewards will be tripled.

However, you cannot choose exactly which Pokémon will appear during sleep research. To make the most of the bonus, it’s worth choosing an area where you have a good chance of encountering Pokémon whose Candy you need.

Ghost-Type Pokémon Receive Special Bonuses

During the event, Ghost-type helper Pokémon will receive the following bonuses:

• +1 ingredient whenever they collect ingredients through regular helping
• 1.25× main skill trigger chance
• +3 main skill levels when their main skills activate

Additionally, one of Snorlax’s three favorite Berries will always be Bluk Berry, the Berry associated with Ghost-type Pokémon.

These bonuses make Ghost-type Pokémon particularly useful for Berry collection, ingredient gathering, and main skill activation.

However, that doesn’t mean you need to build a team of five Ghost-type Pokémon.

For example, Banette can take advantage of the guaranteed Bluk Berry preference to generate Energy. But replacing your healer or essential ingredient specialists just to use more Ghost-types could make your team less effective overall.

I recommend using your strongest Ghost-type Pokémon alongside the helpers you normally rely on.

Pokémon From Other Sleep Types Can Appear

During the event, Pokémon can appear regardless of your sleep type.

This gives you more opportunities to encounter Pokémon that are normally difficult to find because you rarely get their associated sleep type.

It’s a good idea to keep some Biscuits available in case you encounter a Pokémon you’ve been looking for.

Halloween 2026 Featured Pokémon

The following Pokémon will have increased appearance rates during the event.

All featured Pokémon can appear in both Greengrass Isle and Greengrass Isle EX during the event.

Misdreavus, Mismagius, and Halloween Eevee have the highest appearance-rate boost, making this a particularly good opportunity to encounter them.

Misdreavus and Mismagius Make Their Debut

Misdreavus and Mismagius will begin appearing in Pokémon Sleep on October 26, 2026, at 3:00 p.m.

Their new main skill, Mystical Fire (Cooking Advance S), increases the size of the cooking pot for the next meal while also slightly increasing the chance of an Extra Tasty dish.

Because it combines effects similar to Cooking Power-Up S and Tasty Chance S, I find this new skill particularly interesting.

However, several important details have not yet been revealed, including Mismagius’s specialty, base helping time, and main skill trigger rate.

Until those details become available, it’s difficult to determine how strong Mismagius will actually be.

Since both Pokémon will have increased appearance rates during Halloween, I think it’s worth catching a few if you have the Biscuits available.

There’s no need to invest valuable resources before their full performance becomes clear.

Halloween Eevee With a Purple Hat Arrives

Halloween 2026 will also introduce a new Eevee wearing a purple Halloween hat.

You can obtain an Eevee (Halloween) Incense through limited-time event missions.

The Incense can be used starting on October 26, 2026, at 3:00 p.m.

Costumed Pokémon from previous Halloween events may also appear during sleep research.

If you missed any of them in previous years, this could be another opportunity to add them to your collection.

Best Research Area for Halloween 2026

The event will take place on two research areas:

• Greengrass Isle
• Greengrass Isle EX

I recommend choosing based on whether your main priority is catching the new Pokémon or collecting Candy for Pokémon you already want to raise.

Who Should Choose Greengrass Isle?

Greengrass Isle is a good option for players who are still developing their teams or want to earn Snorlax Strength consistently during the event.

If your main goal is to encounter Misdreavus, Mismagius, or Halloween-costumed Pokémon, there’s no need to choose EX just for that purpose.

All featured Pokémon can appear on regular Greengrass Isle as well.

You can still take full advantage of the event’s Candy bonuses without visiting EX.

Who Should Choose Greengrass Isle EX?

Greengrass Isle EX is worth considering if you regularly play there or want to make progress with sleep research in that area.

However, the official announcement does not state that Misdreavus or Halloween-costumed Pokémon receive higher appearance-rate boosts on EX.

Rather than assuming EX is automatically better, I recommend considering which Pokémon you want to encounter there.

If you already have a team that can perform well on EX, it may be a good choice.

Consider How Much Snorlax Strength You Can Earn

Personally, I wouldn’t choose Greengrass Isle EX simply because I have access to it.

The increased Candy rewards are valuable, but the Pokémon you encounter during sleep research will determine how useful those rewards are for your own goals.

If you struggle to earn enough Snorlax Strength on EX, regular Greengrass Isle may be the more comfortable choice.

On the other hand, if you can consistently perform well on EX and have specific Pokémon you want to encounter there, choosing EX makes sense.

Best Pokémon to Catch During Halloween 2026

Several Ghost-type Pokémon will have increased appearance rates, but that doesn’t mean you need to catch all of them.

I recommend prioritizing Pokémon that you expect to use beyond the Halloween event.

Shuppet and Banette: Recommended Berry Specialists

Banette is a Ghost-type Berries specialist, making it a natural fit for an event where Bluk Berry is guaranteed to be one of Snorlax’s favorite Berries.

If you don’t already have a strong Banette, this is a good opportunity to look for one.

When evaluating Shuppet, I would place particularly high value on Berry Finding S.

However, there’s no need to immediately raise every promising Shuppet you catch during the event.

If your current team can already earn enough Snorlax Strength, you can simply keep a good candidate for future use.

Mimikyu: Powerful, but Expensive to Hunt

Mimikyu is another featured Pokémon worth considering.

Its main skill, Disguise (Berry Burst), contributes to Energy production, and Mimikyu will benefit from the event’s Ghost-type bonuses.

However, Mimikyu requires 16 friendship points.

Catching enough Mimikyu to find an excellent individual can consume a large number of Biscuits.

For that reason, I wouldn’t recommend spending all your resources just to hunt Mimikyu during this event.

If you happen to find a good one, it can certainly be worth raising.

Gastly and Gengar: Depends on Your Ingredient Needs

The Gastly evolution line will also receive increased appearance rates.

Gengar is an Ingredients specialist, so it can be worth considering if you’re still missing a reliable supplier for the ingredients you need.

However, if you already have strong Pokémon that can gather those ingredients, there’s no need to replace them just because Gengar receives Halloween bonuses.

I would evaluate Gengar based on how useful it will be for your regular cooking rather than its temporary event performance.

Misdreavus and Mismagius: Wait for Their Full Details

It’s too early to assign a definitive hunting priority to Misdreavus and Mismagius.

Their new main skill is interesting because it affects both cooking pot capacity and Extra Tasty chance.

Since both Pokémon will receive a major appearance-rate boost, catching a few and evaluating them once their full details are available seems like a reasonable approach.

For now, I wouldn’t recommend making a major investment in Mismagius before its actual performance is known.

How to Prepare for Halloween 2026

You Don’t Need to Rush Ghost-Type Training

Ghost-type Pokémon will receive increased main skill trigger rates and main skill levels throughout the event.

However, I don’t think it’s necessary to invest a large amount of resources in Ghost-type Pokémon solely for Halloween.

The event itself provides opportunities to catch Ghost-type Pokémon and collect additional Candy.

That means you can use Halloween to find future training candidates instead of trying to finish raising them beforehand.

If you already have a strong Banette or Mimikyu, training it could be worthwhile. Otherwise, saving your resources is a perfectly reasonable choice.

Save Some Biscuits

One of the most important preparations is making sure you have enough Biscuits available.

Misdreavus and Mismagius are making their debut, and a new Halloween-costumed Eevee will also appear.

Mimikyu and several other Ghost-type Pokémon will receive increased appearance rates as well.

Keeping some Poké Biscuits available will give you more flexibility once the new Pokémon’s performance becomes clear.

Decide Which Pokémon’s Candy You Want

Sleep research Candy rewards will be doubled during most of the event and tripled on October 31 and November 1.

Before the event begins, I recommend thinking about which Pokémon you most want to raise.

For example, you may want Candy for a strong Berries specialist you’re currently training or an Ingredients specialist you’re trying to raise to Lv. 60.

The event isn’t just about catching new Pokémon. It’s also a chance to make progress on Pokémon you’ve already invested in.

You Can Save Your Main Skill Seeds

Ghost-type Pokémon will receive a +3 main skill level bonus during the event.

This means Pokémon with relatively low main skill levels can still benefit from substantially stronger skills while the event is active.

As a result, I don’t think you need to spend Main Skill Seeds solely to prepare for Halloween.

If you’re planning to use a Pokémon for a long time after the event, investing in it may still be worthwhile.

But if you’re only considering the investment for this one week, saving your seeds is probably the better option.

Additionally, Mismagius’s full performance has not yet been revealed.

If you’re thinking about investing Main Skill Seeds in a cooking-related Pokémon, waiting to see how Mismagius performs could help you make a more informed decision.

Final Thoughts: Prioritize Candy and Pokémon You Want to Raise

Pokémon Sleep Halloween 2026 will run from October 26 through November 1, featuring double and triple Candy rewards, Ghost-type bonuses, and the debut of Misdreavus and Mismagius.

I would focus on making the most of the increased Candy rewards and catching Pokémon that could be useful beyond the event.

Banette and Mimikyu are worth considering, while Misdreavus and Mismagius are interesting new additions whose full performance still needs to be evaluated.

There’s no need to rush Ghost-type training just for Halloween.

Choose between Greengrass Isle and Greengrass Isle EX based on your existing team and the Pokémon whose Candy you want, and spend your Biscuits and training resources accordingly.
