- 99 Nights in the Forest is a co-op survival game by Grandma's Favourite Games, and it is one of the most played games on Roblox right now.
- The Trick or Treat Part 1 Halloween event is live from October 17 at 17:00 UTC to October 24 at 12:00 UTC.
- Find costume pieces, wear a full set, and knock on decorated houses at night to earn Candy.
- Spend Candy at Happy's Halloween shop on exclusive decorations, pets, and the Vampire Alpha Wolf.
- The Helping Happy update from October 3 added Happy's Scythe, spider webs, and three more badges.
99 Nights in the Forest dropped its Halloween season in two parts. Helping Happy went live on October 3 and added a rescue quest where Happy the Halloween Guy has been taken apart by The Ram. Trick or Treat Part 1 followed on October 17 and brought back trick-or-treating along with costumes, Candy currency, and a Halloween shop in the lobby. The developer's Roblox event listing shows the Trick or Treat window running from October 17 at 17:00 UTC to October 24 at 12:00 UTC.[1][2]
The game sits high on Roblox's charts. At the time of writing, it holds hundreds of thousands of concurrent players and has over 30 billion lifetime visits.[3] If you have never played, the core loop is simple: you spawn in a forest, scavenge resources, build a camp, and try to survive until rescue. The Halloween event layers a collectible costume and candy system on top of that loop.
Helping Happy: the first Halloween update
Helping Happy is the October 3 update and it is already live. Happy the Halloween Guy has been scattered across the map, and your server has to find his body parts and put him back together.[2]
Here is what the update added:
- Happy's Scythe: a three-level weapon you pick up near the campfire. It is the only tool that can clear the new spider webs.
- Spider webs: these spawn all over the map. Hitting one with a normal weapon gives the message "You need a special scythe to clear this." Webs stop spawning around campfire level 5.
- Three badges: Reaping (level Happy's Scythe to max), Strawcraft (rebuild Happy), and Sweeping (destroy 200 webs with the scythe).
- Happy's Cart: a furniture reward for earning all three Helping Happy badges.
- Four quest structures: a web-covered barn, a timber-framed windmill, a gray stone building, and a fenced pumpkin patch. Each holds one of Happy's limbs.
Trick or Treat Part 1: costumes and Candy
Trick or Treat Part 1 is the second Halloween update and it is the one most players are excited about. Here is how it works.[1][4]
Getting costumes
Costume pieces come from three sources: Costume Boxes found near points of interest like houses and ruins, Halloween themed mobs like Wolves and Cultists, and enemy drops. There are six costume sets: Pirate, Lobster, Astronaut, Dinosaur, Mummy, and Werewolf. You build a Costume Closet at your camp to store pieces and change your outfit.[1][4]
Once you have a costume equipped, you can trick or treat at decorated houses. The game lets you knock on a door at night by pressing E. Without a costume, you are guaranteed to roll a Trick and receive a debuff instead of Candy. That makes finding a costume the first priority when you drop in.[1][4]
Earning Candy
Every costume piece you have equipped gives you 1 Candy when you trick or treat. A full set of four pieces gives 4 Candy. If all four pieces belong to the same set, like a full Werewolf outfit, you get an extra 4 Candy for a total of 8 per house, plus a chance at rare treats like a pet frog.[4]
The key detail most guides miss: costume pieces are consumed when you use them to trick or treat. You need to keep finding new pieces each run if you want to keep farming Candy.[4]
Halloween shop rewards
Happy runs a Halloween shop in the lobby. Here are the rewards and their Candy costs.[4]
[table]
[tr]Reward | Candy cost[/tr]
[tr]Halloween Decor | 10[/tr]
[tr]Spooky Crock Pot | 25[/tr]
[tr]Shrapnel Grenade | 30[/tr]
[tr]Fancy Dressed Clothes | 30[/tr]
[tr]Coffin Chair | 30[/tr]
[tr]Pile of Skulls | 30[/tr]
[tr]Spooky Braziers | 50[/tr]
[tr]Standing Coffins | 80[/tr]
[tr]Candy Corn Bunny | 80[/tr]
[tr]Vampire Alpha Wolf | 200[/tr]
[/table]
The Vampire Alpha Wolf is the most expensive reward at 200 Candy. It is a Halloween skin variant of the Alpha Wolf pet and will not be available after the event ends. The Candy Corn Bunny at 80 Candy is the second priority for collectors.[4]
Badges and the Fancy Dressed class
The Trick or Treat event added three badges.[1][2]
- Candy Collecting: collect your first Candy.
- Carving: carve a pumpkin at a Pumpkin Carving Station.
- Costuming: trick or treat while wearing a full matching costume set.
Pumpkin Carving Stations are scattered around the map. Bring a pumpkin to one, choose a face, and you can take your jack-o-lantern back to camp. There is also a Halloween Furniture Stall that sells seasonal camp decorations.[1]
Farming Candy efficiently
The best Candy farm is a full matching costume set. Eight Candy per house with rare treat chances is double what a mismatched set gives you. Focus on finding Costume Boxes near familiar POIs at the start of each run rather than wandering into unfamiliar areas.[4]
Candy carries between runs and is not lost on death. That means you can accumulate it over multiple sessions and spend it at the shop when you have enough for the item you want.[4]
The Helping Happy webs are worth clearing too. Each web can hold a random item like Pumpkins, Old Radios, Broken Fans, Cultist Gems, Mossy Coins, Coal, Berries, and more. Happy's Scythe makes quick work of them.[2]
