Brunito Marsito has quickly become the most coveted collectible in Roblox’s Steal a Brainrot. Inspired by Bruno Mars’ stylish look from his 2026 hit I Just Might music video, this ultra-rare Secret Brainrot made its debut during the viral Bruno Mars concert event. The unit spawned only once—making it one of the rarest items in the game—and boasts an enormous in-game value of $750 million, producing $3.5 million per second in passive income.

The design closely mirrors Bruno Mars’ concert appearance: brownish skin, neatly trimmed beard, red headband, expressive brown eyes, a green jacket with yellow accents, and brown boots. Recognized for both its visual detail and rarity, Brunito Marsito became available exclusively through the Admin Abuse event’s conveyor belt spawn at the concert’s finale on January 17, 2026. This one-time release turned the Brainrot into a prized symbol of prestige among dedicated players. 

Acquiring Brunito Marsito required speed, strategy, and a bit of luck. During the live event, players had to rush the conveyor belt immediately after the release, grab the unit, and dash back to base while dodging chaotic waves of chasers. After the original spawn disappeared, players relied on the game’s signature theft mechanics—raiding bases, holding E to steal Brainrots, and using traps like spikes to defend their haul. Although trading allows copies to circulate, true ownership remains fiercely contested across public lobbies. Wondering what is the best Brainrot in Steal a Brainrot?
