99 Nights in the Forest Full Costuming is the Halloween 2026 badge for trick-or-treating in every complete costume before night 99. Having every outfit sitting in your Costume Closet is not enough. You need to wear all six matching four-piece sets at a decorated house and finish the visit.
For the 99 Nights in the Forest Full Costuming badge, the goal is to use all six matching outfits at houses before night 99, not squeeze them into one night. Gather costumes across the run, save hard-to-find pieces and keep a simple record of which outfits you’ve already used. There are six themes to work through, and keeping them separate is the biggest time-saver.
How to get 99 Nights in the Forest Full Costuming
Roblox describes the requirement as trick-or-treating with every full costume before 99 nights. The wording doesn’t demand doing all six in one night. For the 99 Nights in the Forest Full Costuming badge, prepare the set, approach an active house at night, knock and wait until the resident finishes responding. Then mark that theme complete.
All six costumes you must use
| Costume set | What counts |
|---|---|
| Pirate | One completed house visit with four matching Pirate pieces equipped |
| Lobster | One completed house visit with four matching Lobster pieces equipped |
| Astronaut | One completed house visit with four matching Astronaut pieces equipped |
| Dinosaur | One completed house visit with four matching Dinosaur pieces equipped |
| Mummy | One completed house visit with four matching Mummy pieces equipped |
| Werewolf | One completed house visit with four matching Werewolf pieces equipped |
A full set consists of four parts from the same theme. Four random pieces aren’t a full set, even when every outfit slot is occupied. The costume guide covers how the pieces fit together and how a matching set increases the normal successful Treat payout to eight Candy.
Where to find the pieces for 99 Nights in the Forest Full Costuming
Search Costume Boxes while exploring points of interest in daylight, and check seasonal enemy drops and chest bonuses. The locations change with each generated forest map, so you won’t have a dependable fixed coordinate for the final Lobster head or Pirate accessory.
Keep difficult-to-replace pieces at the Costume Closet until you have a matching set. The Closet is made from three Wood at a Tier 1 Crafting Bench, and costume pieces do not carry into a fresh run. If you already own three Dinosaur parts, make those the next set to complete rather than scattering your attention across every costume. Our Costume Boxes walkthrough covers efficient daytime routes.
How to use each outfit at Halloween houses
For 99 Nights in the Forest Full Costuming, find a decorated house during daylight and check whether its entrance needs a Halloween Candle to light up. Equip the complete outfit at your Costume Closet, then return after dark to knock. Costume parts are used during trick-or-treating, so you’ll need another complete outfit for your next theme. The house guide covers how residents and door availability work.
Keep a second prepared house near camp in case the first resident is on cooldown. If the first door is on cooldown, visit the other one when it’s ready instead of crossing the whole forest under pressure. The Halloween Candles guide explains the activation item.
How to track 99 Nights in the Forest Full Costuming without losing progress
Write down the six themes and cross one off after each completed interaction. Check the badge screen after a visit if progress is shown, rather than treating a collected outfit as a completed one. This is particularly useful if you swap gear frequently or share supplies with teammates.
The badge wording includes a before-night-99 deadline. Complete the six outfits during one run. The badge’s wording includes the night-99 deadline, and no reliable documentation confirms that partial costume progress survives switching runs. Use the daylight periods to gather missing parts while keeping the camp stocked with food and fuel.
Full Costuming versus Fancy Dressing
The secret Fancy Dressing badge wants a Lobster head, Mummy body, Dinosaur legs and Pirate hook worn together. That’s an intentionally mixed outfit. It won’t replace a complete Lobster, Mummy, Dinosaur or Pirate set for 99 Nights in the Forest Full Costuming. Save spare pieces for that challenge after you’ve secured the required full-outfit visits.
Our Fancy Dressing badge walkthrough explains the exact mixed outfit. The two badges reward different uses of the same costume collection, so one good Costume Box farming run can help with both.
After each completed visit, tick the costume off your list. You’ll know exactly which set still needs a trip to a house.
Why 99 Nights in the Forest Full Costuming might not unlock
Check whether you genuinely visited a house wearing every matching set. Having the clothing in storage, wearing mixed parts or approaching a house that isn’t active won’t satisfy the requirement. Make sure the last visit finished before the game advanced beyond the night limit.
If the badge doesn’t appear straight away, inspect the Roblox badge page and your in-game progress. You may need another qualifying visit for a theme you thought you’d used. Don’t throw away hard-to-find pieces until you’ve verified that part of the challenge.
Can you still earn 99 Nights in the Forest Full Costuming?
The original Roblox Trick or Treat Part 1 listing is scheduled to end on 24 October at 12:00 UTC, but the later badges don’t have a separately verified universal removal date. Check the current event status in the game before committing to a lengthy hunt.
