Jackorilla

Jackorilla is a secret-tier brainrot in Steal a Brainrot, the Roblox collection-and-trading game where every pet generates passive income and can be upgraded with mutations and traits. At base, Jackorilla earns $315.0K/s and costs $80.0M from the in-game shop — those numbers are the floor, before any multiplier from mutations or trait stacking is applied.

It is obtained via Getting from the Spooky Lucky Block in-game. Verify availability before any trade — Steal a Brainrot regularly cycles which items are obtainable, and a brainrot's market value can swing sharply when the game flips it to limited or unobtainable status.

Across live Eldorado marketplace listings, Jackorilla prices currently range from $1 for the Default variant up to $1.75 for Rainbow. Mutation multipliers compound on the base income, so the same Jackorilla body at a higher-tier mutation out-earns its Default variant by exactly that ratio per second.

Current market signals: demand is low, price trend is rising. An unusual combination — Jackorilla has thin demand but its price has ticked up. Often signals a buff, a permanence change, or a small group catalyst. Watch the next few scrapes before treating the new price as the real floor.

For trade evaluation, divide the USD value by your offer's value to get a clean ratio. The trade calculator does this automatically and applies trait amplifiers (Brilliant, Sniper, etc.) which add to base income additively rather than multiplicatively. See the methodology page for how the valuation algorithm actually computes these numbers, or the trade-valuation guide for a step-by-step walkthrough.
