All 5 New Brainrots in Steal a Brainrot Update 51 (Anniversary)

All 5 New Brainrots in Steal a Brainrot Update 51 (Anniversary)

Okay so Update 51 just dropped on May 16, 2026 and I have been grinding non-stop ever since. This is the big 1 Year Anniversary update and the devs went absolutely crazy with it. We got five brand-new brainrots — four are Secret rarity and one is the ultra-rare OG rarity — and some of them are already selling for insane amounts in the trading community.

I am going to break down every single one of them: rarity, income per second, how much they cost, how to actually get them, and my honest take on whether they are worth chasing. Let's get into it.

Quick Stats Comparison

Before I go through each one, here is the at-a-glance comparison table so you can see how they stack up.

Yeah, that Spyder Elephant number is not a typo. One trillion dollars. We will talk about it.

La Anniversary Grande

Rarity: Secret

Income: $50M/s

Cost: $10B standard, or $15B if you craft it through Sammy's Limited Stock Truck

La Anniversary Grande is the face of this whole update and honestly it looks incredible — big anniversary vibes all around. But here is the thing you need to know before you get too excited: this one is Limited Stock.

The devs only made 50,000 copies in the first batch (released May 16) and another 50,000-copy batch on May 19. Once every single copy across both batches is claimed, La Anniversary Grande can never be crafted again. That is it. Done. This is not a scare tactic — it is literally how the game works.

To craft it at Sammy's Limited Stock Truck in the center of the map you need to submit:

• 1x 1x1x1x1 (get it from the 1x1x1x1 Ritual, 94% success rate)
• 1x Lavadorito Spinito (buy from the Red Carpet for $8B)
• 1x La Grande Combinasion (Red Carpet, Sammy's Base, Backrooms event, Cyber Craft Machine, Brainrot Trader, or Admin Lucky Block at 0.5% chance)

After submitting those three you pay $15B to receive your copy. The standard $10B price applies if you manage to obtain it through other means.

My take: La Anniversary Grande is a must-have collector's item more than a pure income machine. $50M/s is solid but not game-changing at high levels. The real reason to own one is the prestige and the fact that it will literally never be obtainable again once stock runs out. If you have the ingredients, do not sleep on this.

Flancito

Rarity: Secret

Income: $3.75M/s

Cost: $800M

Flancito is probably the most accessible of all five new brainrots in this update. At $800M it is within reach for mid-game players and the Secret rarity makes it a nice flex even if the income is on the lower end.

The name is clearly a nod to flan — that classic Latin American dessert — and the brainrot design leans fully into that energy. It is cute, it is silly, and it fits perfectly with the anniversary celebration theme.

My take: Flancito is the starter anniversary pick. If you are not yet rolling in trillions, this is the update brainrot you can realistically aim for right now. The $3.75M/s income will not carry your leaderboard score but having a Secret from the anniversary update in your collection is always worth it. Grab Flancito first and then save up for the bigger ones.

Sammyni Cakini

Rarity: Secret

Income: $85M/s

Cost: $12.5B

Sammyni Cakini is one of my personal favorites from this whole drop. The name is a birthday cake remix of Sammy, one of the most iconic characters in the game, and the design absolutely delivers on that concept.

At $85M/s it sits just behind Jelly Moby among the Secret-rarity additions, and at $12.5B it is expensive but not completely out of reach for late-game grinders. This one also ties directly into the La Anniversary Grande craft because Sammy's Limited Stock Truck is where you pick up the anniversary special — so Sammyni Cakini and that whole system feel connected lore-wise.

My take: Sammyni Cakini is the sweet spot (pun intended) of this update. Great income, reasonable cost relative to what you get, and iconic enough to make your collection look serious. If I had to pick just one Secret rarity anniversary brainrot to grind toward, it would be either this one or Jelly Moby depending on your budget.

Jelly Moby

Rarity: Secret

Income: $175M/s

Cost: $150B

Jelly Moby is the strongest Secret rarity brainrot added in Update 51 and it is not particularly close. $175M/s is a massive number for a Secret, and that income output puts it in conversation with some of the best brainrots in the entire game at this rarity tier.

The catch is that $150B price tag, which is genuinely steep. You are not casually stumbling into Jelly Moby — this is an end-game grind target.

To get Jelly Moby you craft it in the Cyber Craft Machine. The recipe is:

• 1x Capitano Moby + 1x La Food Combinasion
• Alternate recipe: Pancake + Syrup

The alternate Pancake + Syrup route is interesting because it gives players a second path in case the main ingredients are hard to source.

My take: If you are deep into the game and have the resources, Jelly Moby is the best value Secret in this update by far. $175M/s for a Secret is wild. The $150B cost is the real barrier but once you have it, your passive income gets a serious boost. This is the one hardcore grinders should be targeting.

Spyder Elephant

Rarity: OG

Income: $1B/s

Cost: $1T

And here it is. The crown jewel of Update 51. Spyder Elephant is an OG rarity brainrot — one of the rarest tiers in the entire game — and it earns $1 billion per second.

One. Billion. Per second.

The cost is $1T (one trillion dollars) which is absolutely astronomical, but the moment you see that income number you understand why. Spyder Elephant is not a mid-game goal or even a late-game goal. This is an endgame trophy for the most dedicated players in the entire server.

The design is exactly what it sounds like — spider meets elephant — and it has that OG rarity glow that makes every other player in the game stop and stare when you pull it out.

My take: Spyder Elephant is the single most impressive addition in Update 51 and possibly one of the most impressive brainrots ever added to the game. Most players will never own one. If you do own one, you are officially one of the top players on the server. This is a flex piece and a genuine income monster at the same time. Respect to anyone grinding toward this.

Which One Should You Go For First?

Here is my honest recommendation depending on where you are in the game:

• If you are mid-game: Start with Flancito at $800M. It is the only one realistically achievable without heavy grinding.
• If you are late-game: Aim for Sammyni Cakini ($12.5B) for a great income-to-cost ratio, or Jelly Moby ($150B) if you want the best Secret income.
• If you are a collector: La Anniversary Grande is the priority because of the Limited Stock situation — once it is gone it is gone forever.
• If you are an endgame grinder: You already know Spyder Elephant is the goal. Good luck. Seriously.

Final Thoughts

Update 51 is genuinely one of the best updates the game has ever had. Five new brainrots, a limited-stock crafting system, an OG-rarity monster with $1B/s income, and the whole anniversary celebration on top of it. The devs clearly put a lot of work into this one.

My personal ranking of these five from most worth chasing to least (purely based on value and urgency) would be: La Anniversary Grande first because of scarcity, then Spyder Elephant, then Jelly Moby, then Sammyni Cakini, then Flancito. But that is just me — your priorities might look different depending on your playstyle.
