Brunito Marsito is a limited, Bruno Mars–themed brainrot in Roblox’s Steal a Brainrot. It is tied directly to the game’s first in-game concert and exists as a single, secret unit that then circulates between players through stealing.
What Brunito Marsito is and why it matters
Brunito Marsito is a secret-rarity brainrot modeled after Bruno Mars’ look from the “I Just Might” music video. In-game, it appears as a humanoid figure with a brown skin tone, beard, red headband, brown eyes, and a green outfit with yellow details and brown boots, matching the music video’s styling.
The brainrot stands out for two reasons. First, it is limited: the developer only spawns it once during the Bruno Mars concert segment of the Admin Abuse event. Second, it functions as a high-end money unit. Brunito Marsito is valued at $750M and generates $3.5M every second, which places it among the strongest money-making secret brainrots currently available.
Bruno Mars concert timing and context
The Bruno Mars event runs inside Steal a Brainrot as part of a broader Admin Abuse update. The concert window is listed on the Roblox event page as January 17 to January 23, with the kickoff moment on Saturday, January 17. The initial start times are:
- 12 p.m. PST
- 1 p.m. MST
- 2 p.m. CT
- 3 p.m. EST
- 8 p.m. GMT
During the show, Bruno Mars performs “I Just Might” and “Locked Out of Heaven” inside the experience. This appearance is framed as his first “pop-up” in Steal a Brainrot and comes with Bruno-themed traits and the single Bruno Marsito brainrot.
How Brunito Marsito spawns during Admin Abuse
The only official spawn for Brunito Marsito happens during the Bruno Mars concert segment of Admin Abuse. At the end of the concert, the developer character Sammy triggers the spawn on the conveyor belt in a live server.
Only one Brunito Marsito is created during this sequence. Whoever is in the right place at the right time can pick it up as it comes off the belt and add it to their base. There is no secondary, guaranteed drop or shop listing for additional copies tied to the concert itself.
Because concert-scale events can overcrowd Roblox servers, being online, loaded into Steal a Brainrot, and ready on the conveyor belt before the finale is critical. Players who are not in the relevant server when the spawn occurs cannot get that original instance.
Method 1: Being present for the Bruno Marsito spawn
Step 1: Join Steal a Brainrot shortly before the listed Bruno Mars concert start time and remain in-game for the full show so you do not miss the finale sequence.
Step 2: Move to a position where you can clearly see and reach the conveyor belt in your server’s Admin Abuse arena before the concert ends.
Step 3: When Sammy spawns Brunito Marsito on the conveyor belt, approach the brainrot as quickly as possible and claim it as soon as it becomes interactable.
Only one player can secure this original spawn. Every other instance that appears later in the game comes from stealing that same unit after it has been placed in someone’s base.
Method 2: Stealing Brunito Marsito from other players
Once the one-time spawn is claimed, Brunito Marsito spreads through lobbies the way any other brainrot does in Steal a Brainrot: by being stolen from its owner.
Step 1: Queue into public lobbies and look for bases that visibly display Brunito Marsito. Its Bruno Mars styling makes it easy to spot compared to more generic brainrots.
Step 2: Enter the target player’s base and approach Brunito Marsito. When you are close enough, hold the E key to start stealing it. Keep holding until the interaction completes and the unit is in your possession.
Step 3: Once the steal finishes, leave the enemy base immediately and run back to your own base while carrying Brunito Marsito. Expect the original owner to chase you.
Step 4: Before attempting a steal, set up traps around the entrance to your base. When chased, loop around your own traps so the pursuing player runs into them, giving you enough time to secure Brunito Marsito safely inside your base.
This stealing loop is how most players end up with Brunito Marsito after the initial concert. The brainrot can be taken repeatedly from whichever base currently holds it, so its ownership shifts constantly between players who are successful at stealing and defending.
Brunito Marsito stats and economic impact
| Property | Brunito Marsito value |
|---|---|
| Rarity | Secret |
| Unit value | $750M |
| Income per second | $3.5M |
Secret brainrots in Steal a Brainrot are rare by design, but not all of them specialize in raw cash output. Brunito Marsito is positioned as one of the top money units in the secret tier, combining limited availability with high passive income.
A single Brunito Marsito generating $3.5M every second can accelerate a base’s economy dramatically compared with more common brainrots. That economic leverage is why players are willing to invest time and risk to steal it repeatedly from other bases.
Visual design and link to “I Just Might”
Brunito Marsito’s model recreates Bruno Mars’ outfit from the “I Just Might” music video in voxel form. The character’s green jacket and pants, yellow jewelry details, red headband, and boots are all mirrored on the brainrot. Even the face styling and hair covering echo the music video look.
This visual tie-in is part of a broader push inside Steal a Brainrot to make the Bruno Mars concert feel like more than a background playlist. The game uses the brainrot design to bridge the performance, the upcoming album The Romantic, and the core loop of collecting and stealing units.
What to expect once you own Brunito Marsito
After you successfully claim or steal Brunito Marsito and place it in your base, it behaves like other money-generating brainrots. It contributes $3.5M per second to your income stream and carries a high nominal value of $750M, but it is also a constant target.
Other players can invade your base and attempt to hold E on Brunito Marsito the same way you did with theirs. Owning it effectively adds a permanent objective marker over your base, so trap placement, pathing, and base layout become more important if you want to hold onto it for long.
The end result is a loop that fits Steal a Brainrot’s design: one hyper-valuable, celebrity-themed brainrot is created during a one-off concert, then the entire player base competes to steal and defend it over time.
