The Bruno Mars Concert Event
This unit only enters the game through the Bruno Mars Concert, an event that is part of the "Admin Abuse" expansion that runs from January 17 to January 23, 2026.
During the concert, players can watch a voxel version of Bruno Mars go through his hits "Locked Out of Heaven" and "I Just Might." It's not just for show, though it's the birth of the Brunito Marsito unit.
Method 1: Retrieving the Original Spawn
In total, only one original Brunito Marsito is ever spawned per live server during the event, making it among the rarest items in Roblox history.
- Be early, as servers fill up rapidly during Admin Abuse events. Join at least 30 minutes before the concert for a spot.
- Stay right through to the end of the concert, as developer character Sammy appears only during the finale.
- Sammy will trigger a special spawn on the conveyor belt in the Admin Abuse arena.
- When Brunito Marsito shows up on the belt, it becomes a free-for-all. Whoever the first player to interact with that unit could claim him as their own and add him to their base.
Method 2: Stealing Brunito Marsito from Others
Since there is only one original unit per server, most players will acquire their Brunito Marsito by taking him from someone else. Here is the professional way to borrow him:
Step 1: Scouting
Hop between bases in your server. Search for a base with heavy defenses or high-tier players. Since he is in a green outfit with a red headband, Brunito Marsito is very visible from a distance. The highly prepared players also upgrade the movement items and tools from the Brainrot Shop, which can make escaping much easier.
Step 2: The Heist
Enter the enemy base, find the unit. You must stand close to him and hold the 'E' key. A progress bar will appear; once that is done, the unit is in your hands.
Step 3: The Escape
This is the hardest part: the moment you pick him up, the owner will likely get a notification. You gotta get right back to base.
Pro Tip: Use any movement-boosting items or speed-up pads, if available. Carrying a $750M unit makes you a mega target for everyone in the server, not just the original owner.
How to Use Brunito Marsito
Once you've successfully landed Brunito Marsito on your conveyor belt, he will show up in your Inventory. To start using him:
1. Deployment: Open inventory, then click Brunito Marsito; place him anywhere inside your base. Note: He occupies one unit slot, so do make sure you have space, especially if you're early in your rebirth cycle.
2. Passive Income: The moment he is placed, you'll see your cash counter start ticking up by $3.5 million every second. You don't need to click him; the income is fully passive so long as he remains in your base.
3. The Music Stage Synergy: Put him precisely on the Music Stage furniture for the most of him. This enables the "Performance Mode" animation in the update 2026, where he starts dancing and confirms the 1.2x buff, which raises income from $3.5M to $4.2M per second to help you earn much faster.
4. AFK Farming: Some players choose Brunito Marsito for AFK grinding. If you plan to just run the game in the background to accumulate billions, make sure you are in the Private Server or that your Proximity Alarms and Laser Grids are fully powered, as Brunito will still earn income for you while you are away from the keyboard.
How to Safeguard Your Investment
Once you own Brunito Marsito, many players will attack your base because he brings in $3.5M per second in income. To keep him safe, do not just block the front door with a lock but add Laser Grids behind the door; this will reset anyone trying to glitch in. Place proximity alarms around Brunito. which alerts you when someone comes close.
Another clever trick is to use a Cardboard Decoy. Place the decoy in a visible location and hide the real Brunito behind large furniture or in a dark corner. This will cause most thieves to rush in and grab the decoy, allowing you time to react and defend the base.
Conclusion
Brunito Marsito is a symbol of status and economy driver of the 2026 Admin Abuse update. By living out the concert spawn or performing a risky heist, you gain a massive $3.5M/s income source per unit. To ensure this income, use Laser Grids and scale with the Music Stage synergy. Whether you are rising through the leaderboards or gathering rarities, this unit is your way to dominate the Steal a Brainrot meta.
