The Winter Hour update turns Steal a Brainrot into a Christmas factory: Santa shows up in the middle of the map, a special timer ticks down to rare spawns, and almost everything on the conveyor belt suddenly wears a hat. At the center of it all are the Christmas brainrots, a small pool of limited units that print Dollars per Second and disappear once the event wraps.
How Winter Hour Christmas brainrots work
Winter Hour is a timed Christmas event that runs on a strict two-hour cycle. In the event zone, a timer sits next to the Advent Calendar Christmas Tree. When that timer hits zero, one of the event’s Christmas brainrots is spawned or transformed on the central line, depending on the activity you are doing:
- In the core Winter Hour loop, a random Christmas brainrot appears on the conveyor belt. Collect it and carry it back to your base like any other unit.
- Santa also stands in the central plaza. Every two hours, he steps forward and whacks a random brainrot placed in front of him, converting it into its Christmas variant.
- Several Christmas brainrots bypass the timer entirely and arrive through mini-events, the Advent Calendar, or the Santa Fusion Machine.
The event is finite. Winter Hour starts on December 6, 2025, and ends on December 12, 2025, so these units are time-gated and then removed from circulation for the rest of the year.
Winter Hour’s collection goal: unlocking La Jolly Grande
Winter Hour is built around a simple collection goal. Every two hours, one of four specific Christmas brainrots can appear on the conveyor:
- Ballerina Peppermintina
- Reindeer Tralala
- Santteo
- List List List Sahur
Your task is to pick these up, one by one, and make sure you eventually own all four different units at the same time. Once all four have been collected, you can redeem them for the event’s featured reward: the limited La Jolly Grande brainrot.
The spawn is random. It is possible — and common — to see the same Christmas unit multiple times before your set is complete. Duplicates do not progress the collection; you simply wait for the next two‑hour window and hope for a missing one. La Jolly Grande itself is globally limited by a shared in‑game counter. When that counter hits zero, no new copies can be created, even if your personal event time is still running.
All known Christmas brainrots and how to get them
The Christmas update adds a cluster of themed brainrots spread across Winter Hour, the Admin Abuse event, the Advent Calendar, regular map drops, and the Santa Fusion Machine. The table below groups every known unit, its cost, income, and primary unlock method.
| Brainrot | Price | Income | How to obtain |
|---|---|---|---|
| Festive Lucky Block | $0 | $0/s | Admin Abuse event or Advent Calendar |
| Festive 67 | — | — | Not yet specified |
| La Jolly Grande | $3.5B | $30M/s | Winter Hour event (collect Ballerina Peppermintina, Reindeer Tralala, Santteo, and List List List Sahur) |
| La Gingerbread Kepat | — | — | Not yet specified |
| 25 | $250M | $1M/s | 25th day of the Advent Calendar |
| La Ginger Sekolah | $152B | $124M/s | Santa Fuse Machine |
| La Vacca Prese Presente | $150M | $600K/s | Santa Fuse Machine |
| Chicleteira Noelteira | $2B | $15.5M/s | Santa Fuse Machine |
| Cooki and Milki | $100B | $155M/s | Brainrot trail, Festive Lucky Block, or Santa Fuse Machine |
| Giftini Spyderini | $240M | $999.9K/s | Admin Abuse event |
| Ballerina Peppermintina | $37.5M | $215K/s | 5th day of the Advent Calendar, also featured in Winter Hour rotation |
Several of these sit behind overlapping systems. Festive Lucky Block and Cooki and Milki in particular can show up both through special events and via the Santa Fusion Machine, which makes them good candidates if you are leaning on fusions instead of camping specific event windows.
Santa Fusion Machine and Christmas brainrots
The Santa Fusion Machine (also called the Santa Fuse Machine) sits in the center of the map next to the standard Shop. It is a temporary structure that disappears when the event ends on December 12, 2025.
Functionally, it is a lottery for high‑tier Christmas brainrots:
- You place four of your existing brainrots into the machine.
- The machine locks for 15 minutes while it “fuses” them.
- When the timer finishes, you receive a single Christmas‑themed brainrot from a set of 15 possible units, including four Secret‑rarity options.
Unit quality matters. Feeding the machine stronger, more expensive brainrots increases the odds that the result is rarer and more valuable. The Christmas pulls generally outperform what you sacrificed in Dollars per Second, so repeatedly fusing is one of the cleaner ways to scale income during the event.
La Ginger Sekolah, La Vacca Prese Presente, Chicleteira Noelteira, and Cooki and Milki are explicitly tied to this machine and form part of its drop pool. Cooki and Milki can also come from other Christmas systems, but the Fusion Machine is the only named route for the other three.
There is one catch: as soon as the fusion completes, the machine spits the new brainrot out into the open world, and you must physically carry it back to your base. That small walk is a high‑value robbery window. Other players often hover near the machine waiting to steal fresh fusions before they reach safety.
How Winter Hour’s two-hour cycle actually feels to play
While the event headline is simple — a Christmas unit every two hours — the timer shapes how you engage with Steal a Brainrot during the week‑long window. The schedule looks like this:
| Trigger | Effect |
|---|---|
| Every 2 hours | Spawns one random Christmas brainrot on the conveyor belt |
| After pickup | Timer resets and starts counting down to the next spawn |
| After collecting all 4 named event units | Allows you to redeem them for La Jolly Grande |
You do not have to stay online for the full two‑hour gap, but you do need to be present when the timer reaches zero if you want to claim the spawn before anyone else does. The timer is visible next to the Advent Calendar Christmas Tree, so you always know exactly how long you have.
Because the event pick is random, extended streaks of duplicates are possible. Expect to miss a few cycles to bad luck; compensating just means checking in more often and at different times of day so you roll more spins before the event ends.
Advent Calendar Christmas brainrots
The Advent Calendar runs from December 1 to December 25 and quietly hides some of the better early‑game Christmas options. Unlocks are tied to specific days rather than performance:
- Ballerina Peppermintina — Arrives on the 5th day with a purchase cost of $37.5M and an income of $215K/s. It also doubles as one of the four Winter Hour collection units.
- 25 — Drops on the 25th day with a price of $250M and an income of $1M/s.
- Festive Lucky Block — Can be rolled as part of Advent rewards and the Admin Abuse event.
Advent units are straightforward to claim: visit the calendar on the correct day, complete whatever small action or purchase is required, and then walk the reward back to your base. Once the calendar period closes after December 25, these paths are no longer available, and the units become seasonal collectibles.
Admin Abuse event Christmas brainrots
The Admin Abuse event is another limited‑time layer that overlaps with Winter Hour and exposes a different slice of the Christmas pool. Two units are tied to it:
- Festive Lucky Block — A $0 cost, $0/s unit that functions less as an income source and more as a gateway to other rewards. It can be picked up for free during Admin Abuse or through Advent.
- Giftini Spyderini — Costs $240M and produces $999.9K/s. This is a standard income brainrot and only shows up through Admin Abuse.
Cooki and Milki also intersect with these systems. It can appear on the Brainrot trail, drop out of Festive Lucky Block, or arrive from the Santa Fusion Machine, making it one of the more flexible Christmas pickups and a strong candidate for players who lean into every event type at once.
Staying safe while carrying Christmas brainrots
Every system in this update ultimately produces a physical unit you have to transport. That design matters because Steal a Brainrot’s core loop is built around theft: any exposed brainrot can be stolen if the owner is stunned or disconnecting.
Two situations are especially risky during the Winter Hour week:
- Immediately after a Santa Fusion Machine pull. Other players watch the machine and target anyone leaving it with a new brainrot.
- During the 2–5 second window when exiting the game. Your brainrots remain in the world briefly after you hit leave, which makes disconnecting near other players dangerous.
If a Christmas brainrot vanishes from your base, it has almost certainly been stolen rather than lost to a bug, and there is no restoration path. The safest habit is to move new units straight to secure spots in your base, avoid logging out in crowded areas, and treat the Fusion Machine courtyard as contested territory rather than a neutral safe zone.
Winter Hour’s Christmas brainrots turn Steal a Brainrot into a short‑run economy puzzle: juggle a two‑hour timer, feed the Santa Fusion Machine with increasingly better offerings, and race the global La Jolly Grande counter before it hits zero. Once the event closes and the Advent Calendar shuts down on December 25, these units become part of the game’s seasonal history, locked away until the next holiday cycle.
