Blueberrinni Octopusini

Legendary is the entry point for the high-rarity meta in Steal a Brainrot. Legendary brainrots are the first creatures most players unlock that pay back their cost in under five minutes of base income.

Blueberrinni Octopusini pulls a modest $1K/s/sec, which makes it a respectable rebirth-2 staple but a clear fuse-fodder candidate by rebirth 5.

Blueberrinni Octopusini was originally designed by @alexey_pigeon and entered the official Steal a Brainrot roster after the meme spread across short-form video.

Legendary brainrots are reasonably common on the conveyor (around 4-6% with upgraded base) and they're the cheapest input for any Mythic-tier fuse recipe. Most players buy three or four of these, run them as their main income source for a rebirth or two, and then start fusing them up. Apply Gold or Diamond mutation as soon as you can to roughly double the income output.

Costing $250K on the conveyor when it does spawn, Blueberrinni Octopusini sits inside the standard cost-per-income window for the legendary tier; trade values track that ratio closely on community boards.

Cheap mutations like Gold (1.25x) or Lava (1.5x) are the most economical fits — anything more expensive is overinvestment given the ceiling of this rarity tier.

Use Blueberrinni Octopusini as a placeholder while you stack cash for upgrades, then fuse or trade it away once a higher-tier replacement becomes available.
