99 Nights in the Forest is closing out 2025 with a large Christmas and New Year event built around a multi-stage update, a fully decorated winter lobby and forest, and a limited-time event shop. The holiday content builds directly on the early December “New Classes” patch and then rolls out in three stages through the second half of December.
The focus of the event is simple: survive the forest as usual while completing seasonal tasks, collecting a special holiday currency, and spending it on exclusive classes, skins and decorations, with extra diamond codes sprinkled in during the event window.
December 2025 update timeline
Several late‑2025 updates lead directly into the Christmas event. The table below highlights the key dates that matter for the holiday content.
| Date (2025) | Update | Relevance to Christmas event |
|---|---|---|
| 6 December | New Classes | Adds Brute and Explorer, new shields, snowflake particles in the lobby, and a clear teaser that Christmas content is coming the following week. |
| 13 December, 13:00 EST | Major December patch | Scheduled release time for the main December update that kicks off the holiday event on live servers. |
| 14–28 December | Christmas / New Year event | Three-stage holiday event window with the festive lobby and forest, reworked winter biome, event shop and time‑limited rewards. |
Exact start and end times in your region depend on time zone, but the in‑game countdown and server time determine when holiday content becomes active.
New Classes update and early festive changes
The 6 December “New Classes” update is both a content patch and a soft start to the seasonal theme. It introduces two new classes and a pair of defensive items while quietly preparing the game for the full Christmas rollout.
New classes. Brute and Explorer are added to the classes roster. Brute focuses on frontline tanking with high durability, while Explorer is oriented around movement and utility on the map. Both are purchased with Diamonds like other classes.
New shields. Two shields arrive alongside the classes: Brute Shield and Obsidiron Shield. These improve survivability against the increasingly dangerous entities that appear in later nights and in higher‑risk locations.
Snow in the lobby. From this patch onward, snowflake particles fall in the lobby, signalling the approaching event. Apart from small bug fixes, core gameplay remains unchanged here; the big environmental shift happens with the mid‑December patch.
Christmas and New Year map changes
The main December update substantially changes how the hub and forest look and feel during the event window.
Festive lobby. The lobby is transformed with:
- Garlands and Christmas decorations draped around structures.
- Snowmen and heavy snowfall across the central area.
- A thicker blanket of snow on the ground to create a full holiday hub.
The result is an area often referred to as a “festive forest” lobby, which serves as the visual entry point into the event.
Decorated forest. Out in the main play area, the forest also receives a seasonal pass. Tree branches are decorated, lighting is softened to give a warmer glow, and snow falls across the map to create a consistent winter atmosphere rather than limiting it to the hub.
Winter biome rework. During the holiday event, the winter biome is adjusted so players no longer freeze while exploring it. This removes the constant pressure of cold damage and allows groups to spend time in the snow‑covered area to enjoy the environment and complete seasonal objectives without worrying about temperature management.
Festive entities. Several existing entities receive Christmas and New Year themed variants:
- The Deer appears as a Santa‑style reindeer.
- The Owl takes on an elf‑themed appearance.
- The Ram is presented as one of Santa’s helpers.
The Bat remains visually unchanged and keeps its darker cave‑bound role, which fits its underground location where snowfall does not reach.
Three-stage holiday event structure
The Christmas event is structured in three main stages running from mid‑December to roughly the 28th, similar in pacing to the Halloween multi‑week rollout earlier in the year. Each stage adds more tasks and, typically, at least one major mechanic or area focus.
Stage 1 – Gifts and houses. The opening stage centres on collecting gifts scattered around the forest and delivering them to houses. Completing deliveries rewards players in two primary ways: temporary fun effects such as being transformed into a snowman, and the special holiday currency that is required for purchases in the event shop.
Later stages – Additional quests and challenges. The second and third stages build on this base with more event‑specific content. Following the pattern of earlier seasonal events, players can expect new quests, more reasons to revisit existing locations, and additional ways to earn holiday currency and cosmetics as the calendar approaches the end of December.
The three‑stage structure encourages players to log in across multiple days rather than trying to see everything in a single session.
Event shop, holiday currency and daily gifts
A dedicated event shop is one of the main pillars of the 2025 Christmas and New Year content. It operates alongside the existing class and item systems rather than replacing them.
Special holiday currency. Instead of Diamonds or regular loot, the event shop uses a limited‑time holiday currency. Players earn this by taking part in seasonal activities such as delivering gifts, completing holiday quests and interacting with other event mechanics. The currency disappears with the event, so it is intended to be spent rather than hoarded.
Exclusive classes and skins. The shop offers items that are not available through normal gameplay paths while the event is live. These include:
- Exclusive event‑limited classes purchasable only with holiday currency.
- Unique character and entity skins tied to the Christmas and New Year theme.
- Decorative items and furniture to personalise camps and bases in a festive style.
Daily gifts. Every player can claim gifts on a daily basis during the event window. These can include small amounts of currency, cosmetic items or other seasonal bonuses, and are collected directly from the new event shop interface.
Once the event ends, access to the holiday currency and event shop closes, but unlocked classes, skins and decor remain on the account if the design follows previous limited‑time events.
Holiday diamond and event codes (December 2025)
Diamond codes are an important part of the December event. They provide free Diamonds that can be used to buy classes and other upgrades, and occasionally unlock small seasonal bonuses. Some codes are standard text codes entered in a menu, while others behave more like in‑game secrets.
The table below summarises key codes that are relevant around the 2025 Christmas event period.
| Code text | Reward | How it is used | Status (December 2025) |
|---|---|---|---|
afterparty |
15 Diamonds | Standard code; enter in the in‑game Codes menu. | Active in early December 2025. |
yay fishing |
2 Diamonds | Chat phrase; type while fishing after meeting specific conditions. | Active in early December 2025. |
christmaseventupdatenextweek |
Diamonds (event‑linked amount) | Standard code; entered in the Codes menu during the pre‑event period. | Limited‑time pre‑event code from early December 2025; not guaranteed to still redeem. |
happyhalloween |
– | – | Halloween seasonal code; no longer redeemable in December 2025. |
Holiday codes can also be tied to milestones such as community member counts or specific days in the event calendar, and some have hard usage limits, so they can stop working even while the event is technically still running.
How to redeem standard diamond codes
Most codes, including afterparty and event‑style strings such as christmaseventupdatenextweek, are redeemed through the same in‑game menu.
Step 1: Launch Roblox and open 99 Nights in the Forest, then wait until you are fully loaded into the lobby.
Step 2: Click the Diamonds (gem) icon in the bottom‑left corner of the screen to open the Diamonds menu.
Step 3: In the menu that appears, click the blue Codes button in the bottom‑right corner.
Step 4: Check that the interface shows an option labelled “Enter code” and a green Submit button. If it says “Enter merch code” instead, disable the merch checkbox or close that sub‑menu so you return to the normal code entry field.
Step 5: Carefully type the code text exactly as it is written. These codes are generally expected to be entered in lowercase; avoid extra spaces unless the code explicitly contains one.
Step 6: Click Submit. If the code is valid on your account and has not expired or hit a use cap, your Diamonds balance will increase immediately.
Joining the official 99 Nights in the Forest Roblox group and playing on an up‑to‑date server can help avoid issues where a very new code appears as invalid simply because the server has not yet received the latest update.
How to activate the “yay fishing” code
The yay fishing code works differently from standard diamond codes. It acts as a hidden phrase that only grants rewards once you are actively fishing in a run.
Step 1: Start a new solo or multiplayer game and load into the forest as usual.
Step 2: Upgrade the campfire to Level 2 so that fishing content and related structures can appear.
Step 3: Find the fishing cabin or house with a pond that contains fishing rods. Pick up an Old Rod (or other available rod).
Step 4: Go to a fishing hole where you can see the water surface react to casting. Use the rod to cast your line so that your bobber is in the water.
Step 5: While your line is cast, open the experience chat (for example by pressing the chat key on PC or tapping the chat button on mobile).
Step 6: Type yay fishing exactly like that, with a space between the two words, and send the message.
Step 7: If all requirements are met, you receive 2 Diamonds shortly after sending the phrase, in addition to any normal fishing rewards.
Because this code is tied to an in‑game action rather than the lobby interface, it only works when your character is actively fishing as described above.
Using the event to progress your account
The 2025 Christmas event is designed to be both a celebration and a strong progression window. Holiday currency and daily gifts are most useful if they are spent, not saved, and the temporary boost in available diamonds from codes makes it easier to unlock classes that usually require longer grinding.
Before the main event stages begin, it is worth ensuring that key systems such as your campfire level and access to important locations like the winter biome and fishing cabin are unlocked. Entering the event with at least a few versatile classes already purchased makes it easier to tackle new tasks and to farm the currency needed for exclusive seasonal rewards.
Because both the event shop and many codes are time‑limited, checking for new codes and logging in regularly during the 14–28 December window is the most reliable way to see everything the 2025 Christmas and New Year event has to offer.
