99 Nights in the Forest brings back its Trick or Treat Halloween event for 2026, and it runs only through October 31. The setup sounds simple: find a costume, knock on decorated houses, collect Candy, spend it in the shop. But skip the costume or mix up your outfit pieces and you'll walk away with debuffs instead of loot. This guide covers every mechanic, the full shop price list, and the fastest way to stack Candy before the event closes.
How does the Trick or Treat event work?
The moment you load into a run during the Halloween event window, the map transforms. Pumpkins, Halloween decorations, and event-specific structures appear across the environment. None of that matters, though, until you have a costume equipped.
Without a costume, interacting with decorated houses at night guarantees a Trick outcome. That means zero Candy and an active debuff on your character. Equip at least one costume piece before you start knocking on doors.

Once costumed up, walk to a decorated house at night and press E to knock. Each successful interaction rewards you with Candy, the event's dedicated currency. Candy persists between runs and is not lost on death, so every piece you collect counts toward your shop total.
How to get costumes in 99 Nights in the Forest?
Costumes spawn in two reliable places each run:
- Costume Chests near points of interest like houses and ruins
- Halloween-themed mobs, including Wolves and Cultists, which can drop costume pieces on defeat
Once you pick up a piece and equip it, your character visually changes to reflect the costume. There are six costume sets available: Pirate, Lobster, Astronaut, Dinosaur, Mummy, and Werewolf.
The practical implication here: check the costume chests near familiar POIs at the start of each run rather than wandering unfamiliar areas. Efficient chest routing saves time and gets you into candy farming faster.
What's the best way to farm Candy fast?
The difference between 4 Candy and 8 Candy per house visit comes down entirely to your costume setup. Here's how the math works:
- Each individual costume piece rewards 1 Candy when used at a house
- A full set of 4 pieces gives 4 Candies
- A full matching set (all 4 pieces from the same costume, like all Mummy or all Pirate) triggers a mega luck and candy boost, yielding 8 Candies per house plus a chance at rare bonus drops like a pet frog
Mismatched sets are strictly worse. If you have two Pirate pieces and two Dinosaur pieces, you get 4 Candy total with no bonus. Holding out for a complete matching set before hitting houses doubles your return.

For players targeting the Vampire Alpha Wolf at 200 Candy, this efficiency gap adds up fast. Spending extra time at the start of a run to complete a matching set is almost always worth it.
If you want to understand how other progression systems interact with your runs, the modifier flames guide explains how to stack run bonuses that can complement your event farming.
What are the event badges and how do you unlock them?
Three Halloween-specific badges are available during the event, each rewarding Diamonds on completion.
| Badge | Unlock Condition |
|---|---|
| Candy Collecting | Collect your first Candy |
| Carving | Carve a pumpkin |
| Costuming | Trick or treat with a full costume set |
The Carving badge requires you to interact with pumpkins scattered around the environment, which is a separate activity from trick or treating at houses. Don't overlook it since the Diamond reward contributes to your permanent progression totals. Complete all three badges as early in the event window as possible.
For players who want to maximize Diamond income across all available activities, the daily quests guide covers how to stack quest rewards alongside event badges.

What can you buy in the Halloween shop?
The Halloween shop (run by Happyy) is accessible from the lobby during the event window. Everything in it is exclusive to this event and unavailable after October 31.
| Reward | Candy Cost |
|---|---|
| Halloween Decor | 10 |
| Shrapnel Grenade | 30 |
| Fancy Dressed Clothes | 30 |
| Coffin Chair | 30 |
| Pile of Skulls | 30 |
| Spooky Crock Pot | 25 |
| Spooky Braziers | 50 |
| Standing Coffins | 80 |
| Candy Corn Bunny | 80 |
| Vampire Alpha Wolf | 200 |
The Vampire Alpha Wolf at 200 Candy is the headline reward. It's a Halloween skin variant of the Alpha Wolf pet and will not return after this event ends. The Candy Corn Bunny at 80 Candy is the second priority for collectors.
If you're targeting the Vampire Alpha Wolf, budget your Candy carefully. At 8 Candy per house visit (matching set), you need 25 successful trick or treat attempts to hit 200. That's achievable across multiple runs, especially since Candy carries over between sessions.
