Four fresh Secret-tier brainrots have arrived in Steal a Brainrot, and they all tie back to the game’s summer rotation. Gelato Lumacho, Aquarino, Chicleteira Surfeiteira, and La Summer Grande each generate large amounts of passive cash when placed in your base, with La Summer Grande sitting at the top of the group.
Quick answer: The newest Secret brainrots are Gelato Lumacho ($400M cost / $1.4M/s), Aquarino ($865M / $4.2M/s), Chicleteira Surfeiteira ($2.1B / $16M/s), and La Summer Grande ($15B / $60M/s). They are unlocked through the game’s summer content, with the Summer Fuse machine bringing new brainrots to discover.
The four new Secret brainrots and their values
All four of these brainrots are classified as Secret, the second-highest rarity tier in the game, just below OG. The first number is the in-game purchase cost, and the second is the income the brainrot produces per second once placed.
| Brainrot | Rarity | Cost | Income |
|---|---|---|---|
| Gelato Lumacho | Secret | $400M | $1.4M/s |
| Aquarino | Secret | $865M | $4.2M/s |
| Chicleteira Surfeiteira | Secret | $2.1B | $16M/s |
| La Summer Grande | Secret | $15B | $60M/s |
La Summer Grande is the standout. At $60M per second, it earns far more than the other three combined, which matches its much higher $15B cost. Chicleteira Surfeiteira is the middle option at $16M/s, while Gelato Lumacho and Aquarino fill the entry points into this batch.
How Secret rarity compares to other tiers
Steal a Brainrot uses eight rarity tiers, running from Common up through OG. Secret sits near the very top. Knowing where these four land helps explain why their income figures are measured in millions per second rather than the single dollars you see from early-game units.
| Rarity tier | Cost range | Income range |
|---|---|---|
| Common | $25 – $1.7K | $1/s – $14/s |
| Rare | $2K – $9.7K | $15/s – $75/s |
| Epic | $10K – $47.5K | $75/s – $325/s |
| Legendary | $50K – $347.5K | $300/s – $1.9K/s |
| Mythic | $350K – $5.5M | $1.9K/s – $18.5K/s |
| Brainrot God | $5M – $76M | $17.5K/s – $317.5K/s |
| Secret | $50M – $400B | $300K/s – $400M/s |
| OG | $450B – $1T | $450M/s – $1B/s |
All four new brainrots fall inside the Secret band. La Summer Grande’s $15B price tag sits comfortably within that range, while its $60M/s income is on the stronger end for the tier without reaching OG territory.
How to get the new brainrots
These brainrots are tied to the game’s summer content. The Summer Fuse machine returned in a recent update and brought a batch of brand-new brainrots to unlock, and the 1x1x1x1 Room was set to stay available until the Summer Update arrives.
Across the game, there are several ways to add brainrots to your collection:
- Buying them off the conveyor belt (Red Carpet) as they spawn.
- Stealing them directly from other players’ bases.
- Crafting or fusing existing brainrots into a better one through a fusion machine.
- Joining Admin Abuse events, which often release the rarest units.
- Opening Lucky Blocks purchased with Robux.
- Spinning the wheel or opening the Advent Calendar.
Because Secret-tier units spawn on the Red Carpet at extremely low rates, fusing and event participation are usually faster paths than waiting for one to appear on the belt.
Confirming a brainrot is yours
The game keeps an in-game index that tracks every brainrot you have owned at least once. Once you obtain one of these four, it is marked as collected in that index, and the mark stays even if you later sell or lose the brainrot.
Note: Several brainrots are limited-time or limited quantity. After an event ends, those units become legacy items held only by players who got them during the window, so completing the index can be difficult if you miss a release.
Protecting high-value brainrots
Once you place a Secret brainrot in your base, it can be stolen by other players, which matters a lot when a single unit earns tens of millions per second. A few habits reduce the risk.
With La Summer Grande leading the group on raw income and the other three offering cheaper entry points, this batch gives players climbing toward the Secret tier several new targets to chase through the summer rotation. Keep an eye on the Summer Fuse machine and the fusion recipes, since that is where the newest units tend to surface first.
