The secret tier is where the real competition starts in Steal a Brainrot. These are the units that make other players stop and look twice when they walk into your base. They are hard to find, expensive to buy, and almost impossible to steal from someone who knows what they have.
Getting even one top-end Secret brainrot puts you ahead of the majority of players in any server you join. You can check out the Steal a Brainrot store to get your preferred brainrots.
Top 10 Rarest Secret Brainrots
We listed down the top 10 rarest secret Brainrots alongside the income per second it will earn and what it will cost you.
| Rank | Brainrot | Income/sec | Cost |
| 1 | Dragon Cannelloni | $200M | $200B |
| 2 | Headless Horseman | $175M | $150B |
| 3 | Capitano Moby | $160M | $125B |
| 4 | Burguro And Fryuro | $150M | $75B |
| 5 | La Secret Combinasion | $125M | $50B |
| 6 | La Casa Boo | $100M | $40B |
| 7 | Fragrama and Chocrama | $100M | $40B |
| 8 | Spooky and Pumpky | $80M | $25B |
| 9 | Los Spaghettis | $70M | $20B |
| 10 | Spaghetti Tualetti | $50M | $15B |
1. Dragon Cannelloni
Income: $200M/sec | Cost: $200B | Divine: $2B/sec
Dragon Cannelloni is the best Secret brainrot in the entire game right now. Nothing else in the Secret tier comes close to its $200 million-per-second base income. It is the unit every serious player is chasing and the one most people will never actually own through normal gameplay.
There is no easy way to get Dragon Cannelloni. It does not drop from any active event or fuse machine at the moment. The only realistic paths are finding it on the conveyor belt at an almost impossible spawn rate, trading for it with other high-value units, or stealing it from someone careless enough to leave their base unprotected. A Divine Dragon Cannelloni sitting in your base at $2 billion per second is the single most powerful non-OG setup in the game.
2. Headless Horseman
Income: $175M/sec | Cost: $150B | Divine: $1.75B/sec
Headless Horseman is ranked second not just because of income but because of how few copies actually exist. Only 138 of them are in the entire game across every server. That number makes it arguably the hardest Secret brainrot to obtain, regardless of the price tag.
It originally came from the Witch Fuse event, with a maximum 7% pull rate, and required four Secret brainrots as materials. That event is gone and will never come back. The only way to get a Headless Horseman now is through trading or stealing one from a player who already has it. Every copy that gets deleted or abandoned makes the rest even rarer.
3. Capitano Moby
Income: $160M/sec | Cost: $125B | Divine: $1.6B/sec
Capitano Moby sits just below Headless Horseman in income and is one of the hardest Secret brainrots to spot in any server. When one does appear on the conveyor belt, it disappears within seconds. Most players who have one got it through trading rather than natural spawns.
The Divine version at $1.6 billion per second makes it one of the most valuable units in the entire game outside of the OG tier. If you ever get a trade offer that includes Capitano Moby, take it seriously.
4. Burguro And Fryuro
Income: $150M/sec | Cost: $75B | Divine: $1.5B/sec
Burguro and Fryuro are two of the stronger newer additions to the top-end Secret tier. It earns $150 million per second, which puts it firmly in the conversation with the units above it, and its cost of $75 billion is noticeably lower than Capitano Moby and Headless Horseman, which makes it a more realistic trade target for players building up.
If you are working your way toward Dragon Cannelloni, Burguro, and Fryuro are smart stepping stones. Own this first, then use it as trade value to climb higher.
5. La Secret Combinasion
Income: $125M/sec | Cost: $50B | Divine: $1.25B/sec Source: Lucky Box only
La Secret Combinasion is an exclusive Lucky Box. You cannot buy it off the conveyor belt, and it does not come from any fuse machine. The only way to get it outside of trading or stealing is to open Secret Lucky Boxes and hope it drops. Secret Lucky Boxes cost 2,399 Robux each, which makes this one of the most expensive units to chase through normal means.
Because supply is permanently tied to how many Lucky Boxes players open, the total number of copies in the game grows slowly. That keeps it rare even as the game adds new content around it.
6. La Casa Boo
Income: $100M/sec | Cost: $40B | Divine: $1B/sec
La Casa Boo is one of two Secret brainrots sitting at the $100 million-per-second mark. It has a strong reputation in the community and is consistently harder to find in active servers than its income number alone would suggest. Players who own one tend to hold onto it because replacing it would be difficult.
The Divine version surpasses $1 billion per second, putting it in a category very few players ever reach. If you find one at a fair trade value, do not pass it up. However, if you're finding it hard, you can always buy a cheap Steal a Brainrot account for sale.
7. Fragrama and Chocrama
Income: $100M/sec | Cost: $40B | Divine: $1B/sec
Fragrama and Chocrama sit level with La Casa Boo on every stat. Same income, same cost, same Divine value. The two units are effectively equal in power, so choosing between them is purely a matter of personal preference.
Both are strong long-term holds, and both will retain trade value as the game continues to grow. Getting either one of these into your base means you are earning more per second than the vast majority of players you will ever share a server with.
8. Spooky and Pumpky
Income: $80M/sec | Cost: $25B | Divine: $800M/sec
Spooky and Pumpky is a seasonal Halloween unit that is no longer available through any active method. Once the event window closed, it became trade-or-steal-only, meaning the total supply is frozen. No new copies are entering the game.
That seasonal lock is what pushes it onto this list. The income is high on its own, but the fact that it simply cannot be obtained through normal gameplay anymore makes every existing copy more valuable over time. If someone offers you one in a trade, the real question is what they want in return.
9. Los Spaghettis
Income: $70M/sec | Cost: $20B | Divine: $700M/sec
Los Spaghettis is one of the strongest actively tradeable Secrets that does not require a dead event or Lucky Box to obtain. It sits at $70 million per second, which puts it well above most of the Secret-tier units players encounter during regular grinding.
This is a realistic mid-game target for players who are serious about climbing the income ladder. Get Los Spaghettis first, use it to generate cash faster, then work toward the top five on this list through trading.
10. Spaghetti Tualetti
Income: $50M/sec | Cost: $15B | Divine: $500M/sec
Spaghetti Tualetti is the entry point into the real top end of the Secret tier. At $50 million per second, it already earns more than almost every other brainrot on the list. Getting one into your base is a genuine milestone that most players never reach.
From here, the path is clear. Use Spaghetti Tualetti to earn faster, save up, and trade up toward Los Spaghettis and beyond. Every unit on this list is a stepping stone to the one above it.
Conclusion
The top 10 rarest Secret brainrots in Steal a Brainrot are not just the hardest to get. They are the ones that define where you stand in the game. Dragon Cannelloni leads the pack at $200 million per second. Headless Horseman sits second because only 138 copies exist in the entire game. Everything below them follows a clear ladder that rewards patient trading over lucky spawns.
If you are serious about climbing, start with Spaghetti Tualetti, hold it, trade up, and keep going. The top of the Secret tier is reachable. It just takes time, smart trades, and knowing exactly which units are worth chasing.
