Ketupat Bros

Ketupat Bros sits in the elite income band — at $145M/s per second it earns more in a single minute of base time than most early-game lineups produce in an hour, and it scales massively with the right mutation stack.

Ketupat Bros was originally designed by skitbot tobi and entered the official Steal a Brainrot roster after the meme spread across short-form video.

Acquisition is brutal: you'll either spend tens of millions of cash buying through the conveyor (and need luck even with the buy-all setup), pull it from a Secret-only egg or event reward pool, or fuse it from God-tier inputs in the right machine. Most secret brainrots are also locked behind specific events, so missing the window means waiting for a re-release.

Costing $65B on the conveyor when it does spawn, Ketupat Bros sits inside the standard cost-per-income window for the secret tier; trade values track that ratio closely on community boards.

Stack a Diamond, Bloodlust, or Cyber mutation on top and the multiplier compounds the base figure dramatically — the Cyber 11x mutation in particular turns this brainrot into one of the few pieces capable of paying back any base-upgrade cost in under sixty seconds.

If you're chasing a top-tier base lineup or building toward a 6+ rebirth account, securing Ketupat Bros should be a priority — it earns its spot in any secret-tier slot on the leaderboard.
