Steal a Brainrot Wiki Rebuilt: 409 Brainrots Indexed, Cyber Confirmed as Top Mutation at 11×

Last Verified: May 3, 2026. Brainrot data sourced via ETL from stealabrainrot.fandom.com Category:Brainrots (455 pages, 409 with parseable infoboxes). Mutation multipliers verified against the Fandom Mutations master page on the same date. Cost and income-per-second come from in-game shop UI; trade values and spawn probabilities are deliberately not published.

Two Steal a Brainrot wiki pages on bloxguidesgg.com flipped from noindex placeholder to real, searchable databases today. Both have been pointing-at-Fandom stub pages since April 2026, when our zero-fabrication audit pulled the previous tables for using unsourced numbers. The rebuild brings them back with verified primary-source data.

• Brainrot Database — 409 brainrots with rarity, cost, income/s, ritual chains, and obtainable status. Auto-synced from Fandom on every site build.
• Mutations Table — 14 multipliers across Permanent, Limited, and Scrapped tiers. Cyber (11×) is now the top obtainable mutation after Disco was marked scrapped on Fandom.

Here's what's actually on each page, what changed about Disco vs Cyber, and the honesty rule that keeps trade values off both pages.

The 409-Brainrot database — what's there

The Brainrot Database indexes every brainrot with a parseable Fandom infobox — 409 of the 455 entries in Category:Brainrots. The 46 we don't index are family/group/disambiguation pages (e.g., "Mastodontico Family", "Brainrot Trader") rather than individual brainrots.

Per brainrot we surface: rarity, in-game cost (in $), income per second (in $/s), obtainable status, ritual yes/no with ritual name, creator (TikTok / YouTube origin), and release update when the brainrot was added.

The rarity tiers and counts as of today's sync:

The Secret tier being the largest is the surprise here. Most player-facing rarity discussion fixates on the Brainrot God and Mythic tiers because those are obtainable in normal play. Secret tier is mostly event-locked or limited-time content that compounds over time — 220 entries is a lot of historical event content.

Filtering on the page covers the main ways players actually search:

• By name — partial-match search across all 409 brainrots
• By rarity — narrow to a single tier (e.g., "show me only Brainrot God brainrots")
• By obtainability — currently obtainable (396) vs. limited or removed (13)
• By ritual — has-ritual (24) vs. no-ritual

One thing the page does not include: trade values. More on that below.

Mutations: Disco scrapped, Cyber takes the top slot

The Mutations Table is 14 entries hand-curated from the Fandom Mutations master page (the wikitable mixes four different templates, so we hand-curate this small dataset rather than trying to ETL it). Three sections:

Permanent mutations (always available)

Limited mutations (event-locked)

The Disco situation

This is the news for veterans. Disco was a top-tier 11× mutation that we covered as the highest-income mutation as recently as our May 2 Taco Tuesday post. Sometime between then and today's verification, Disco was marked scrapped on the Fandom Mutations master page — meaning new copies cannot be obtained. Brainrots that already have a Disco mutation retain the multiplier, but you can't roll Disco from any active source going forward.

Cyber (11×) is now the highest currently obtainable mutation. They were tied at 11× before; with Disco out, Cyber stands alone at the top. Strategically that means: if you have a Disco-mutated brainrot, hold it (it's now a finite supply). If you're chasing top-multiplier income, Cyber Event is your target.

If your existing strategy was built around Disco, this isn't a nerf to the brainrots you own — it's a removal of one obtainment path. Existing Disco mutations are now locked-supply and likely to appreciate as a result.

Rituals: 24 brainrots with combine chains

Rituals are one of the more interesting Steal a Brainrot mechanics: combine specific brainrots to spawn a rarer variant. 24 of the 409 brainrots in our database have ritual chains, and the database surfaces each ritual's name when you hover the Ritual badge.

Two examples that show up in the database:

• Bombardiro Crocodilo + others → Los Crocodillitos ritual (Mythic-tier)
• Tralalero Tralala participates in a Tralalero ritual chain (Brainrot God-tier)

The "Brainrots with rituals" Fandom category ties everything together — if a brainrot is in that category, it's part of at least one combine chain. Filter the database by "Has ritual" to see all 24 at once.

Why we don't publish trade values

Both pages have a prominent "no trade values" disclaimer. Same reasoning we applied to Grow a Garden, Adopt Me, and Pet Simulator 99:

• Trade values shift every update. A new event drops, demand for a Brainrot God collapses, the static value list goes stale within hours. We can't keep numbers accurate at any sane refresh cadence.
• Demand is a community signal, not a number. Active trading Discords with real W/F/L tracking are where current values live. A static codebase can't replicate an active marketplace.
• Spawn probabilities aren't dev-published. Fandom may show numbers in some infoboxes, but those are community estimates. We won't publish what we can't trace to a primary source.

What we do publish from Fandom: cost (the brainrot's purchase price) and income/s (its passive earning rate). Both come from the in-game shop UI when you inspect a brainrot. They are displayed game stats, traceable to the screen of the game itself. Fandom community editors mirror them within hours of each patch.

For live trade values, the honest pointers are: large Steal a Brainrot trading Discords (which maintain value sheets updated by traders watching real W/F/L outcomes), dated YouTube trade videos posted after the latest update, and on-the-spot value-checks against multiple sources before any large trade.

Where the data comes from (and why it stays current)

The Brainrot database is sourced via a custom ETL script that pulls from stealabrainrot.fandom.com's MediaWiki API and parses the {{Brainrot Infobox}} templates on each page. It runs as part of every Vercel build, so the page reflects whatever Fandom has at deploy time.

Between deploys, a daily diff cron at 08:00 UTC fetches the current Fandom roster, compares it to our committed data, and posts to a Discord channel only when actually-new brainrots appear. Family pages, disambiguation pages, and meta labels are filtered out so the alert signal-to-noise ratio stays high.

The Mutations table is hand-curated rather than auto-synced — 14 entries with quarterly change cadence doesn't justify parser complexity for a wikitable that mixes four different templates. The page shows a "last verified" date so staleness is visible. When a new mutation event ships (the typical trigger for table updates), we re-verify against the in-game collection menu and the Fandom master page.

Update 49 brainrots — automatic coverage

Update 49 dropped May 2 with new brainrots that the community catalogued on Fandom within hours. Because the ETL pulls from Fandom on every build, those Update 49 brainrots are automatically in the database now. No manual list-keeping required.

If you spot a brainrot from Update 49 (or earlier) that's missing, two likely reasons:

• Fandom hasn't catalogued it yet (community editors are usually fast but not instant)
• The Fandom page exists but doesn't have a {{Brainrot Infobox}} template — the ETL needs that to extract structured data

The daily cron will surface either case as drift, and the next site build picks up the fix.

FAQ

How many brainrots are in Steal a Brainrot?

409 brainrots are catalogued on the Fandom wiki as of May 3, 2026, with structured infobox data we can index. The full Category:Brainrots count is 455, but 46 of those are family/disambiguation pages rather than individual brainrots. Numbers shift with every update.

What is the best mutation in Steal a Brainrot right now?

Cyber at 11× is the highest currently obtainable mutation. Disco was tied at 11× until recently but is now marked scrapped on Fandom — existing Disco mutations retain the multiplier, but new copies aren't obtainable.

What's the rarest brainrot tier?

Brainrot God is the top tier with 82 entries — many require rituals to obtain and several are tied to rebirth progression. Secret tier has the most pets (220), but most are limited or event-only rather than rare in the rarity-difficulty sense.

How do mutations work in Steal a Brainrot?

Each brainrot can have at most one mutation applied. The mutation multiplies its income-per-second by the multiplier shown on the Mutations Table. Permanent mutations (Default, Gold, Diamond, Rainbow) can spawn at any time; Limited mutations require active in-game events that activate periodically.

What egg or ritual gives Los Crocodillitos?

Los Crocodillitos is a Mythic-tier ritual variant of Bombardiro Crocodilo. The ritual combines Bombardiro Crocodilo with other specified brainrots; the exact combine list is documented on the Bombardiro Crocodilo Fandom page. Filter the database by "Has ritual" to see all 24 ritual chains.

Why don't you publish trade values?

Trade values shift every update and require an active marketplace to track honestly. Static value pages go stale within hours of any major event. We focus on the canonical in-game data (cost, income/s, rarity) that doesn't change between trades. For live values, large SaB trading Discords are the best current source.

Are Update 49 brainrots in the database?

Yes. The ETL pulls from Fandom on every site build, and community editors typically catalogue new update brainrots within hours of launch. If a brainrot is missing, it's likely still being documented — the daily cron flags drift the next morning.

Where does this data come from?

The Brainrot database is ETL'd from stealabrainrot.fandom.com's MediaWiki API on every site build. The Mutations table is hand-curated from the Fandom Mutations master page, with a "last verified" date for staleness visibility. Cost and income-per-second values come from the in-game shop UI as mirrored on Fandom.

Both pages live now: Brainrot Database and Mutations Table. The Steal a Brainrot hub at /games/steal-a-brainrot ties the rest of the SaB content together: tier lists, codes, strategy guides, and the rest.
