Cerberus

Cerberus 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, Cerberus earns $175.0M/s and costs $150.0B from the in-game shop — those numbers are the floor, before any multiplier from mutations or trait stacking is applied.

This brainrot was first added in Update 33. It is obtained via Red Carpet 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, Cerberus prices currently range from $2.34 for the Default variant up to $9.5 for Cyber — a 4.1x spread reflecting the multiplier gap between mutation tiers. Mutation multipliers compound on the base income, so the same Cerberus body at a higher-tier mutation out-earns its Default variant by exactly that ratio per second.

Current market signals: demand is terrible, price trend is falling. Cerberus's market is soft right now: low buyer activity and a falling median price. Sellers are likely to keep dropping list price to find takers; buyers can usually negotiate below the listed value.

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.
