99 Nights in the Forest Trick or Treat Event Guide

99 Nights in the Forest transforms the spooky season into an immersive hunt across its eerie woodland landscape. Players eager to plunge into this year’s Trick or Treat event will find themselves collecting costumes and candy while navigating decorated houses — a festive challenge that adds fresh twists to the survival experience.

The Trick or Treat event in 99 Nights in the Forest brings Halloween activities, exclusive costumes, and limited-time rewards to the survival game. During this seasonal event, players can explore the forest, search for costume pieces, visit decorated houses, and collect Candy to spend in Happy’s Halloween Shop. Several rewards are only available during the 2026 Halloween event, making it worth collecting enough Candy before the event ends.

In this guide, you will learn how to start the Trick or Treat event, find costumes, earn Candy efficiently, unlock Halloween badges, and purchase every available reward. Following these steps will help you make the most of the event without wasting your Candy on items you do not need.

Jumping into the Trick or Treat event is as simple as logging on during the Halloween window. The forest is transformed with festive decorations, pumpkins, and themed structures waiting to be explored. But the catch? You need to don a costume before your Candy hunt begins, as the event currency won’t drop without it.

After equipping your costume pieces, navigate through the forest to uncover Halloween-themed houses scattered around. Knocking on these doors grants you Candy in exchange for your costume items. All Candy earned can be traded at Happy’s Halloween Shop, where exclusive decorations, equipment, and cosmetics await.

Be cautious, though—approaching these houses without a costume at night results in a debuff rather than Candy. So always gear up properly before your Trick or Treat runs.

Once you have collected and equipped costume pieces, explore the map to locate Halloween-themed houses. These buildings allow you to knock on their doors and receive Candy in exchange for your costume pieces. You can then spend the currency at Happy’s Halloween Shop in the lobby to obtain exclusive decorations, equipment, cosmetics, and other seasonal items.

One important detail is that you can still attempt Trick or Treat without wearing a costume at night. However, doing so guarantees a Trick instead of Candy, which applies a debuff to your character. Therefore, always equip a costume before visiting decorated houses if you want to earn event currency efficiently.

Costumes are the gateway to earning Candy during the event. While surviving is key, don’t overlook the importance of scavenging costume pieces from loot containers and event mobs lurking in the forest. These pieces add up to complete outfits that boost your Candy earnings significantly. Two primary avenues lead to costume collection: searching Costume Chests scattered near points of interest like ruins and houses, and defeating Halloween-themed enemies such as Wolves and Cultists that drop costume parts.

Costumes are essential for participating in the Halloween event because they determine how much Candy you can earn from each house. You can find costume pieces while exploring the forest, so pay attention to loot containers and enemies instead of focusing entirely on survival objectives. Collecting multiple pieces will help you complete costume sets and increase your Candy earnings.

There are two main ways to obtain costumes during the event:

• Costume Chests: Search around points of interest, including houses, ruins, and other structures scattered across the map.
• Halloween-themed enemies: Defeat event-related mobs, such as Wolves and Cultists, to find costume pieces.

Once you have costume pieces, equip them to change your character’s look and unlock Trick or Treat eligibility. The event offers various costume themes, including Pirate, Lobster, Astronaut, Dinosaur, Mummy, and Werewolf. Gathering a full set from any theme is particularly rewarding, amplifying Candy payouts and the chance of bonus goodies.

Just remember, every piece you use during Trick or Treat is consumed, meaning the hunt for new costume parts is continual if you want to keep farming Candy.

Keep in mind that costume pieces used for Trick or Treat are consumed during the interaction. Each equipped piece can be used only once, so you will need to collect more costumes if you want to continue farming Candy. This makes exploring the forest and searching for additional Costume Chests an important part of the event.

When night falls and your character is suited up, seek out the festively decorated houses across the map. Interaction is simple: approach and press E to knock. Candy rewards depend on how well your costume pieces match. Each costume piece nets one Candy, but a full set of four matching pieces doubles that payout and improves your odds of extra treats, like obtaining a pet frog.

Once your character is wearing a costume, look for decorated houses throughout the map. These buildings are the main locations where you can exchange costume pieces for Candy. Trick or Treat interactions must be performed at night, so wait until nighttime if you are exploring during the day. Approach the door and press E to knock and start the interaction.

The amount of Candy you receive depends on the costume pieces you have equipped. Each individual piece provides one Candy, while wearing a complete matching set gives you an additional bonus. A full outfit containing four matching pieces can therefore reward you with eight Candy from a successful interaction, with a chance to receive additional rewards.

• Mismatched costume pieces grant one Candy each.
• Four pieces from the same set yield four Candy plus an additional four Candy bonus.
• Complete matching sets further increase your Candy haul and the chance for special bonuses.

So prioritizing complete costumes definitely pays off in the long haul.

• Mismatched costume pieces: Each piece provides one Candy.
• Four costume pieces from the same set: You receive four Candy from the pieces and an additional four Candy as a matching-set bonus.
• Full matching costume sets: These provide a greater Candy reward and a chance to obtain extra treats, including a pet frog.

Try to collect complete costume sets instead of equipping random pieces whenever possible. Although mismatched outfits still provide Candy, the matching-set bonus makes it easier to build up your currency for expensive Halloween rewards.

How to Farm Candy in 99 Nights in the Forest

Candy is your currency lifeline during the Trick or Treat event, essential for acquiring the best rewards in Happy’s Halloween Shop. The fastest way to stack your stash is to combine costume farming with Trick or Treat runs — loot chests, slay Halloween enemies, and coordinate full costume sets before hitting the decorated doors.

Full matching sets are your best bet, rewarding you with eight Candy per interaction. Mismatched pieces still produce Candy but require more frequent visits and cost more time.

A complete matching outfit is particularly useful because it provides eight Candy per successful interaction under the listed reward rules. If you use mismatched pieces, you will receive less Candy, which means you may need to complete more interactions to reach your target. Always check your equipped costume before knocking on a house to make sure you are getting the best possible reward.

• Focus on assembling full costume sets for the biggest Candy bonuses.
• Explore thoroughly—check houses, ruins, and points of interest for Costume Chests.
• Hunt Halloween-themed enemies like Wolves and Cultists for additional costume parts.
• Never attempt Trick or Treat at night without a costume to avoid debilitating debuffs.
• Spend your Candy wisely, prioritizing expensive rewards over cheap decorations initially.

The Vampire Alpha Wolf pet is the priciest item at 200 Candy, so save up accordingly before splurging.

• Prioritize matching costume sets: Collect four pieces from the same costume theme to activate the extra Candy bonus.
• Explore points of interest: Search houses, ruins, and other structures for Costume Chests.
• Defeat Halloween enemies: Look for Wolves, Cultists, and other event-themed mobs that may provide costume pieces.
• Avoid Trick interactions without a costume: Attempting to Trick or Treat without wearing a costume at night guarantees a Trick and a debuff rather than Candy.
• Spend Candy carefully: Check the Halloween shop before making purchases, especially if you are saving for expensive exclusive rewards.

The Vampire Alpha Wolf costs 200 Candy, making it the most expensive item listed in the Halloween shop. If you want to obtain it, focus on farming full costume sets and avoid spending your currency on cheaper decorations until you have reached your target.

Alongside Candy rewards, event badges offer Diamond prizes for completing key activities, providing alternative goals and progress markers. They’re simpler to earn than collecting vast quantities of Candy, so chasing badges is a smart parallel objective. The event badges include: Candy Collecting: Obtain your first Candy during the event. Carving: Complete a Pumpkin carving. Costuming: Perform a Trick or Treat while wearing a full costume set. Each badge unlocks naturally as you explore, encouraging you to engage with multiple facets of the event without heavy Candy investment.

The Halloween event includes special badges that reward players with Diamonds for completing specific activities. These achievements are relatively simple compared with the process of collecting enough Candy for the most expensive shop items. Completing them early is a useful way to make progress while exploring the event and gathering costume pieces.

There are three event badges to work toward:

• Candy Collecting: Collect your first Candy during the Trick or Treat event.
• Carving: Carve a Pumpkin to complete this achievement.
• Costuming: Perform a Trick or Treat interaction while wearing a complete costume set.

Each badge has a different requirement, so you can work on them naturally while progressing through the event. Collecting your first Candy should be easy once you have equipped a costume, while the Costuming badge requires you to assemble a matching set before visiting a house.

Make sure you complete all three achievements during the Halloween event window. They provide additional rewards and let you experience more of the seasonal content without requiring you to spend large amounts of Candy.
