If you’ve been grinding Steal a Brainrot lately, you’ve probably seen someone flexing a half-human, half-dragon creature in the trade plaza and wondered what on earth it was. That’s Caylusaurus, and it’s one of the few Brainrots in the game right now that genuinely lives up to the hype surrounding it.
This guide breaks down everything worth knowing about Caylusaurus: how it’s obtained, what it earns, and whether it’s still worth chasing now that the event behind it has closed.
What Is Caylusaurus?
Caylusaurus is a Secret rarity Brainrot introduced during a guest-hosted Admin Abuse event on June 6, 2026. Instead of the usual Saturday host, Roblox creator Caylus ran the event himself, and Caylusaurus was the centerpiece reward.
Visually, it’s a fusion design — the upper body is built directly from Caylus’s own Roblox avatar, while the lower half is a full red dragon body, complete with claws, wings, spikes, and a tail. Think of it less like a typical dragon Brainrot and more like a centaur, except the horse half got swapped for a dragon.
The design isn’t random either. It’s a near-direct port of Caylus’s own in-game Brainrot from his other title, Survive Lava for Brainrots, where a creature by the same name already existed. So technically, Caylusaurus had a “first life” before it ever showed up in Steal a Brainrot.
A small but interesting detail: Caylusaurus is only the second Brainrot in the game whose in-game voice line doesn’t actually say its own name out loud — the first being 1x1x1x1. It’s also the second Brainrot ever based on a real streamer, following Steakini Fattini (based on Steak), making this guest-host event format a genuine first for the game’s creator collaborations.
Caylusaurus Stats
| Stat | Value |
| Income | $55,000,000 per second |
| Cost | $12,500,000,000 |
| Rarity | Secret |
| Status | Unobtainable (event ended) |
| Released | Update 53 / Caylus Admin Abuse |
| Fire Trait | Cannot be applied (with one exception below) |
A table is worth showing here because the math behind these numbers is genuinely impressive. At $55M/s, Caylusaurus pays back its own $12.5B cost in roughly 227 seconds — under four minutes. For comparison, most Brainrots at this price point take far longer to break even. Once it crosses that point, a single Caylusaurus earns more in a minute than most mid-progress bases produce in an hour.
How to Get Caylusaurus
There were two routes while the event was live, and understanding both matters even if you’re reading this after the fact, since the same pattern repeats with future guest-host Brainrots.
Method 1: Taco Truck Crafting
This was the primary and most reliable method. Players needed to gather three specific Brainrots first:
- Burrito Bandito
- Nuclearo Dinossauro
- Money Money Puggy
Once all three were collected, taking them to the Taco Truck (also referred to as the Fuse Machine recipe for this event) combined them into one Caylusaurus. Notably, all three crafting materials share an “aura theme” — Burrito Bandito leans gangster, Nuclearo Dinossauro is built around warplane and Tyrannosaurus imagery, and Money Money Puggy is a literal pile of cash. That’s not a coincidence; the devs clearly built this recipe around a consistent visual identity rather than throwing random ingredients together.
Method 2: Stealing
Since stealing is a core mechanic of the entire game, any player who already owned a Caylusaurus was a target. This route didn’t require the crafting materials at all, but it came with the obvious risk of competing against everyone else who wanted the same thing.
Why You Probably Can’t Get One Now
Caylusaurus falls under Limited Quantity Brainrots, meaning supply was capped once the event ended. Stock went out in waves — an initial 5,000 in lucky servers, another 5,000 shortly after, then a 50,000 restock, a further 25,000, and a final 15,000 batch at the close of the event. That puts the total in-game supply somewhere around 100,000 copies, which sounds like a lot until you remember how many active players this game has.
Since the guest Admin Abuse format is a one-off event rather than a recurring schedule, there’s no confirmed path for Caylusaurus to return. If you don’t already have one, trading or stealing from another player is currently the only option.
Mutations and Maximizing Value
This is where a lot of newer players leave value on the table. A plain Caylusaurus is a solid Brainrot on its own, but the real income jump comes from mutations.
A Cyber mutation alone applies an 11x multiplier, pushing income from the base $55M/s up to roughly $605M/s. In actual gameplay during the event window, well-mutated and trait-stacked Caylusaurus units were reported reaching the 1.7B–2.6B+ per second range — a massive gap from the base stats.
The mutations generally considered worth investing trait-farming time into are:
Gold mutations are decent but typically fall short of top-tier value, so most experienced traders don’t recommend heavy trait investment unless your roll is one of the six above.
The Fire Trait Exception
Caylusaurus shares an unusual restriction with Dragon Cannelloni: it cannot receive the Fire Trait under normal play. This isn’t a bug — it’s because the Fire Biome simply wasn’t active during the window Caylus’s Admin Abuse ran, so there was never an opportunity for it to roll naturally.
There’s one workaround: if all three crafting materials (Burrito Bandito, Nuclearo Dinossauro, and Money Money Puggy) already carry the Fire Trait before crafting, the resulting Caylusaurus inherits it. In practice, this is rare and usually only achievable by players who were already trait-farming before the event started.
Is Caylusaurus Worth Trading For?
If you’re weighing whether to spend resources acquiring one through trade now that crafting is closed, a few things matter:
Scarcity drives the value. Limited Quantity Brainrots from closed, one-off events are historically the hardest to reacquire later, which keeps trade demand high even months after release.
Mutation quality matters more than ownership alone. A base Caylusaurus is a respectable collector’s piece, but if you’re trading away multiple high-tier Brainrots for one, make sure you’re getting a Cyber, Rainbow, Lava, Galaxy, Radioactive, or Cursed roll — anything weaker won’t justify the trade cost long-term.
Watch for scam listings. High-value, limited-supply Brainrots like this one attract fake trade offers. If someone won’t show the Brainrot directly in the trade window before finalizing, treat the offer as suspicious.
Frequent Asked Question
Can you still get Caylusaurus today?
No. The event has ended and the crafting route is closed. The only ways to get one now are trading with another player or stealing it from a current owner.
How much income does Caylusaurus generate?
At base stats, it earns $55,000,000 per second. With a Cyber mutation, that jumps to roughly $605M/s, and top-tier trait-stacked units have been reported reaching the 1.7B–2.6B+ per second range.
What Brainrots were needed to craft Caylusaurus?
Three Brainrots were required: Burrito Bandito, Nuclearo Dinossauro, and Money Money Puggy. Combining all three at the Taco Truck produced one Caylusaurus.
Why can’t Caylusaurus get the Fire Trait?
Because the Fire Biome wasn’t active during the event window, so the trait never had a chance to roll naturally. The only exception is if all three crafting materials already carried the Fire Trait before crafting — in that case, the resulting Caylusaurus inherits it.
How many Caylusaurus units exist in total?
Around 100,000 copies, released in waves of 5,000 + 5,000 + 50,000 + 25,000 + 15,000 during the event.
Which mutations give the best value?
Cyber, Rainbow, Lava, Galaxy, Radioactive, and Cursed are the six mutations considered top-tier. Gold mutations are decent but fall short of these.
How do you avoid scams when trading for one?
Always make sure the other player shows the actual Caylusaurus directly in the trade window before finalizing. If they refuse, treat the offer as suspicious.
Quick Recap
Caylusaurus is a Secret-rarity, creator-themed Brainrot tied to a single guest-hosted event, earning $55M/s at base value with a sub-four-minute payback time. It was obtainable only through Taco Truck crafting (Burrito Bandito + Nuclearo Dinossauro + Money Money Puggy) or stealing, and both routes are now closed since the event has ended. The only way to get one today is trading or stealing from a current owner — and if you’re chasing top value, a strong mutation matters far more than the base stats alone.
