Examen Bros in Steal a Brainrot: Stats, Los Traders Recipes & Is It Worth Crafting (2026)

Two exam papers standing side by side, one crying over a big red F, the other grinning next to a gold star and an A, is not the kind of image you’d expect to find worth billions in a Roblox game. But that’s exactly what Examen Bros is: a Secret-rarity Brainrot that turns two of the game’s most contradictory characters into a single, tradeable duo. It joined Steal a Brainrot with Update 59 on July 25, 2026, and unlike most of the update’s other additions, you can’t just wait for it to roll onto the Red Carpet. You have to build it.

This guide covers what Examen Bros actually is, its confirmed cost and income, every known Los Traders recipe that produces it, and whether the ingredients are worth the trouble compared to just saving up cash for something else.

What Is Examen Bros?

Examen Bros is a duo Brainrot made of baby versions of two existing characters: Noo My Examine and Yess My Examine. According to the Steal a Brainrot Wiki, the pairing leans entirely into their contrast — Noo My Examine is modeled as a failing exam paper with a bright red F, correction marks scrawled across it, and a crying expression, while Yess My Examine sits beside it as the passing version, a green-checked A paper with a cheerful face. Put together, they’re built around the same joke: one character failed, the other passed, and now they’re stuck standing next to each other forever.

Sammy leaked Examen Bros ahead of Update 59’s release, which is part of why the community had already been watching for it before it actually went live. It’s also notable for being only the second baby Brainrot in the game whose “parent” characters originally came from a ritual rather than a standard spawn, following Los Hackers as the first.

Examen Bros Stats: Cost, Income, and Rarity

Here’s the confirmed data on Examen Bros, cross-checked against the Steal a Brainrot Wiki and Update 59’s patch notes:

Stat	Confirmed Value
Rarity	Secret
Type	Duo Brainrot
Cost	$20,000,000,000 ($20B)
Income	$70,000,000/second ($70M/s)
Update Introduced	Update 59 (July 25, 2026)
Obtain Method	Los Traders (crafting/trade-in)
Leaked By	Sammy, prior to release

At $70 million per second, Examen Bros earns the same rate as a handful of other Secrets the wiki lists alongside it, including Sammyni Fattini, Rubrikiko, and Los Spaghettis, which puts it solidly in the middle of the Secret tier rather than at the very top or bottom.

How to Get Examen Bros From Los Traders

Examen Bros doesn’t spawn naturally, which means camping the Red Carpet won’t get you one. It’s obtained exclusively through Los Traders, the trade-in system that sits on a raised platform in the middle of the map next to the Summer Fuse Machine. Instead of buying it outright, you hand over a specific set of Brainrots as ingredients, and Los Traders converts them into Examen Bros.

There’s a real timing element here. Los Traders’ stock refreshes every 30 minutes, but that stock is shared across every server in the game, meaning popular offers can disappear fast once word gets out that Examen Bros is currently available. If the offer isn’t showing when you check the board, you’re waiting for the next restock cycle rather than forcing it to appear.

Outside of trading, Examen Bros can also be obtained the same way almost anything else in the game changes hands: by stealing it from another player’s base once someone else has already crafted one and left it undefended.

The Confirmed Examen Bros Recipes

Los Traders rotates between three possible recipes for each Secret it offers, and Examen Bros is no exception. Two of its recipes are fully documented by the community wiki:

Recipe	Ingredients Required
Recipe 1	1x Noo My Examine + 1x Guest 666
Recipe 2	1x Noo My Examine + 1x Coco and Mango
Recipe 3	Partially confirmed — includes Los 67, Yess My Examen, and John Doe, with one ingredient still unverified

Notice that two of the three recipes call for Noo My Examine specifically, which is the harder half of the duo to source. Noo My Examine only comes from the Dul Dul Dul ritual at roughly a 5% pull chance, and with an estimated exist count sitting around 10,000 copies total, it’s genuinely scarce. If you’re planning to craft Examen Bros, sourcing a spare Noo My Examine is realistically the bottleneck, not the second ingredient.

Why Noo My Examine Got Buffed Because of This Brainrot

One detail that’s easy to miss: Update 59’s patch notes specifically buffed Noo My Examine’s income to $32.5 million per second, and the notes tie that buff directly to its role in Examen Bros’ recipes. Since two of the three known trade-ins consume a Noo My Examine, the developers apparently adjusted its base income so players trading one away wouldn’t feel like they were giving up a unit that had fallen behind. It’s a small but useful signal that Los Traders’ ingredient list isn’t arbitrary — the game’s balancing decisions are actively shaped by what feeds into these recipes.

Examen Bros and the Phantom Mutation Chance

Every successful Los Traders exchange carries a roughly 10% chance of the resulting Brainrot spawning with the Phantom mutation instead of its default look, and Examen Bros isn’t excluded from that roll. A Phantom-mutated unit earns 12 times the cash of a standard version, which on a $70M/s base would push Examen Bros closer to $840 million per second if you’re lucky enough to land it. There’s no way to force this outcome; it’s applied automatically the moment the trade completes. For a full rundown of how Phantom compares to the game’s other mutation options and what else it affects, the site’s Phantom Mutation guide breaks down the mechanic in more detail.

Is Examen Bros Worth Crafting?

On raw income, $70M/s for a $20B trade-in sits in reasonable territory compared to other Update 59 additions. It earns considerably less than Pizza and Ranch, which produces $130M/s at a similar $55B price point, but it also costs less than a third as much, which matters if you’re not sitting on tens of billions yet. Compared to Toro Españolo, the cheapest of Update 59’s new Secrets at $555M, Examen Bros is a much bigger investment for a proportionally bigger payout.

Where Examen Bros actually stands out isn’t pure income, it’s the crafting angle itself. Because it requires a genuinely scarce ingredient in Noo My Examine, it’s one of the harder Secrets to reproduce, and that scarcity tends to hold trading value better than units that anyone can eventually save up cash for on the Red Carpet.

Should You Trade for It or Skip It?

If you already own a spare Noo My Examine sitting in storage, crafting Examen Bros is close to a no-brainer, since you’re converting an underused unit into a Secret with real passive income and a shot at a 12x Phantom roll. If you don’t own one, the math changes: you’d need to either win the Dul Dul Dul ritual’s roughly 5% chance yourself or buy/trade for a Noo My Examine first, which adds real time and cost on top of the $20B trade-in itself.

For collectors focused on trading rather than farming, Examen Bros’ value is likely to track its scarcity going forward. Since it’s locked behind a limited-supply ingredient rather than a simple spawn roll, exist counts should stay lower than brainrots obtainable straight off the conveyor.
