On May 16, 2026, Steal a Brainrot turned one year old. Update 51 is how the developers marked it — two new Brainrot characters, a limited-time anniversary event, and a new Trait. The standout addition is La Anniversary Grande, a cake-wielding Brainrot with one of the more absurd weapon designs the game has produced.
One year ago this was a meme-cycle experiment. It peaked at 25.8 million concurrent players in October 2025 — fifth-highest in Roblox history — and it's still pulling 400K to 600K daily players in May 2026. That's a real game now, and Update 51 is a signal that the developers intend to keep it that way.
La Anniversary Grande — Full Profile
La Anniversary Grande is the headline Brainrot of Update 51. It's a cake-themed character — fitting for a birthday — and it wields a giant pink blaster arm as its primary weapon. In a game built on absurdist character design, it stands out even by Steal a Brainrot's standards.

Everything Added in Update 51
New Brainrot Characters
Update 51 added two new Brainrot characters to the game. La Anniversary Grande is confirmed and detailed above. The second new character has not been officially named in the sources available at time of writing — check the Brainrot Database for the most current roster.
New Trait
A new Trait was added in Update 51. The specific name and mechanics of this Trait were not included in available patch summaries at time of writing.
⚠️ Note: Steal a Brainrot's Trait system affects how Brainrots behave and interact — a new Trait is a meaningful addition to the meta. The Mutations Table covers the multiplier system; Traits operate separately as character-behavior modifiers. Community testing in the official Discord is typically where Trait mechanics get documented first.
Limited-Time Anniversary Event
A limited-time event is running alongside Update 51 to mark the one-year milestone. Specific rewards and event duration have not been officially detailed. Event end date is unconfirmed.
Anniversary Event — What to Do Now
Limited-time events in Steal a Brainrot follow a standard pattern:
- Log in daily — most Steal a Brainrot events include login-based rewards. Don't skip days.
- Play during Admin Abuse events — the developers run elevated-reward sessions twice a week (see schedule below). Anniversary events often have bonus Admin Abuse sessions or special reward pools.
- Check the official Discord — event end dates and any special mechanics are announced there first, before Fandom or guide sites pick them up.
- Prioritize La Anniversary Grande — if she's event-exclusive or has a limited-time acquisition window, that's the primary thing to target before the event ends.
Active Codes — May 2026
There are no active redemption codes for Steal a Brainrot as of May 18, 2026. The game has historically issued codes sparingly — they're more likely to appear around major events than as a regular cadence.
Check the Steal a Brainrot Hub for any new codes posted after this article's publish date.
Admin Abuse Schedule
Admin Abuse events are the highest-reward sessions in Steal a Brainrot — the developers join live servers and run elevated drop rates and special content. The regular schedule:
| Day | Time | Notes |
|---|---|---|
| Tuesday | 6:00 PM ET | Regular weekly session |
| Saturday | 3:00 PM ET | Regular weekly session |
Anniversary periods sometimes add extra sessions or extend existing ones — follow the official Discord for any schedule changes around Update 51.
One Year of Steal a Brainrot — By the Numbers
May 2026 marks 12 months since Steal a Brainrot launched on Roblox. The trajectory is worth understanding:
| Milestone | When | Notes |
|---|---|---|
| Game launched | May 2025 | Original brainrot-meme wave concept |
| All-time CCU peak | October 2025 | 25.8 million concurrent — 5th highest in Roblox history |
| Update 51 | May 16, 2026 | One-year anniversary |
| Current daily CCU | May 2026 | 400K–600K |
Most games that spike on meme energy don't last six months. Steal a Brainrot's sustained player count past its peak indicates something beyond the initial viral wave — the developers kept updating, the community stayed engaged, and the trading/collection loop gave players a reason to return.
The Mutation Meta — Where Things Stand
The current top of the mutation hierarchy for most players is Cyber (11x), following Disco (12x) being marked as scrapped on the Fandom wiki. If you're building toward the highest reachable multiplier, Cyber is the target.

Grow a Garden 2 Sugar Egg Preview: Muffin Man (Super, 0.1997%), Fat Cat, Chocolate Lab, Sugar Bunny & the Four Muffin Gears Landing August 22, 2026
Grow a Garden 2's next drop is the Sugar Egg, releasing on August 22, 2026 with four new pets and four still-mysterious Muffin gears. The wiki has already filled in every pull rate: Sugar Bunny at 49.8752% (Common — hops around and gives +5 walk speed and +5 jump height at base), Chocolate Lab at 29.9551% (Uncommon — sniffs out a 1% free duplicate whenever you buy a seed, capped at 10%), Fat Cat at 19.97% (Rare — lounges around and scales your character size, x1.15 at base up to x1.625 on a Mega Rainbow), and the chase Muffin Man at 0.1997% (Super — every 10 minutes goes on a Sugar High, making everything you sell worth 1.25x for 10 seconds, with variant boosts capped at +70% on a Mega Rainbow). Four themed Muffin gears (Blueberry, Pumpkin, Carrot, Gold) are also dropping the same day but every effect on the wiki is still TBA — we flag every unknown honestly. Speaking as someone playing GaG2 since launch, this is the first pet-focused RNG since Fall Harvest's Shadow Dragon rush, the Muffin Man passive is the first true "active" sell-multiplier the game has ever shipped, and the raw math on cutting 500 Sugar Eggs at 0.1997% each is uglier than the tier headline suggests. Here is the full wiki-cited breakdown — every rate, every variant scaling table, and the honest opportunity cost of chasing Muffin Man vs. banking Sheckles for whatever Sunday brings.
Steal a Brainrot Update 62 REBIRTH 19 Guide: La Fuse Machine (95M/s Secret), Candini Fluffini (57.5M/s), Grief Shield Gear, the 28th Base Slot & What Actually Changed the Day After Launch (August 16, 2026)
Steal a Brainrot Update 62 — the REBIRTH 19 update — went live on August 15, 2026 and the wiki has now filled in every number. The rebirth wall itself asks for $30 Qa cash and one La Grande Combinasion Secret brainrot and pays back with an x19 income multiplier, a $250T cash bonus, +10 seconds of base-lock time, and the 28th base slot the community has been asking for since Rebirth 17. Two brand-new Secret brainrots hit the RNG Machine: La Fuse Machine ($95M/s income, 35B cost, blocky blue robot with cyan accents, the first brainrot literally themed on one of the game's own machines) and Candini Fluffini ($57.5M/s income, 14B cost, a pastel-blue voxel lamb with an ice-cream cart on its back), both from creator BRAZILIAN SPYDER. The Rebirth 19 gear unlock is the Grief Shield — a one-hit shield that soaks a griefer's slap but explicitly does NOT protect the person you're actively stealing from, which will surprise anyone who thinks they can hoard-run with it. Timers on every Lucky Block are gone, meaning you can pop them the second you buy them, and the new RNG Machine Luck slot exists but is Admin-Abuse only, non-purchaseable. This is the day-after playbook: the honest math on whether Rebirth 19 is worth pushing tonight, the La Fuse Machine vs Candini Fluffini price-per-income breakdown, why the Grief Shield changes early-Rebirth defense but not late-game stealing, and what to hoard before Update 63 lands on August 22.
Grow a Garden Harvest Moon Part 3 Is LIVE: Every Robux Buy-Outright Price, Every Full Craft Recipe & What Bountiful, Threshing, Lunarbound and Starry Pet Mutations Actually Do (August 15, 2026)
Grow a Garden's Harvest Moon Event Part 3 goes live on August 15, 2026, and every number that was TBA in yesterday's preview is now wiki-confirmed. Buy-outright Robux prices are locked in: Starry Strawberry Seed 99, Moonbeam Radar 199, Wheat Crow 289, Wheatcap Seed 199, Harvest Golem 699, Harvest Melon Seed 719. Every crafting recipe has its full ingredient list — Harvest Golem is the recipe that will make veterans blink because it eats a Moon Egg AND a Mythical Egg AND a Burning Bud AND a Romanesco plus 70 Moon Coins, while Harvest Melon requires a Moon Chest on top of three seed ingredients and 120 Moon Coins. And the four new pet mutations finally have their real passive lines filled in: Bountiful is 15% XP + 5–10% Night-fruit duplication (x20 sell), Threshing is 15% passive + 6–12% tool preservation (x30), Lunarbound is 20% XP + 130% size + 2.5–5% Moonbound-on-collect (x50), and Starry is 25% passive + 25% XP + a 20–40s cooldown reduction on a random pet ability every 2–4 minutes for every Starry pet in your garden (x80). This is the launch-day rundown: how the Robux prices actually stack up per hour of grind saved, why Harvest Golem is the ceiling craft that most veterans will chase first, and the honest read on whether the buy-outright button is ever worth it. As someone with thousands of hours in the original Grow a Garden, this is what to do the moment Part 3 loads in.
