Steal a Brainrot St. Patrick's Update — All 8 New Brainrots, Mutation & Pot of Gold Skin

Update 42 is live. The Steal a Brainrot St. Patrick's Day update dropped today — March 14, 2026, at 12:00 PM PT / 3:00 PM ET — and it's packed with new content. Eight new brainrots via the Leprechaun Lucky Block, a brand-new mutation, the limited-time Pot of Gold Base Skin, and a recurring Lucky Pot event that rains gold across servers every two hours.

This is the second major update in just one week, following the Divine Fuse Machine update on March 7 that added 15 new brainrots, the Trade Machine, and the Divine Mutation. The pace of content is accelerating — and if you're not collecting these limited-time St. Patrick's brainrots now, you'll regret it later.

Here's everything you need to know.

All 8 New Leprechaun Lucky Block Brainrots {#new-brainrots}

The Leprechaun Lucky Block is the centerpiece of Update 42. It contains eight new brainrots split across two rarity tiers — Brainrot God and Secret:

Brainrot God Tier

Secret Tier

Six out of eight are Secret rarity. That means the pull rates are extremely low — expect to burn through a lot of attempts before landing them all. Patteo is the most common pull, so don't be surprised if you get multiples of that one before seeing anything else.

With this update, the total brainrot count climbs to approximately 355+ (up from ~347 before Update 42).

---

Lucky Pot & Lucky Block Event {#lucky-pot-event}

This isn't just a new Lucky Block — there's a server-wide event tied to it.

How It Works

The ST PATRICKS Lucky Pot + Lucky Block event triggers every two hours and activates:

Raining Gold Trait — A server-wide trait that showers gold across the map

Rainbow Event — Visual effects and bonus rewards for all players on the server

Random Luck Multiplier — Boosts your chances on Lucky Block pulls during the event window

Cloverat Clapat Spawn — A rare NPC with a small chance of appearing during the event

When you see the Lucky Pot event activate, drop everything and start pulling. The luck multiplier during this window is your best shot at landing those Secret-tier brainrots.

New Mutation {#new-mutation}

Update 42 introduces a new St. Patrick's-themed mutation to the game. While the exact mechanics are still being discovered by the community, early reports suggest:

Colorful visual effects tied to the St. Patrick's theme

Special upgrades that enhance certain brainrots

Expected to follow the existing mutation multiplier system

Current Mutation System

For context, here are the existing mutations and their multipliers:

Collecting all obtainable brainrots with a single mutation type unlocks a corresponding base color, so completing this new mutation's collection could unlock a new base appearance. We'll update this section as the community discovers the full details.

---

Pot of Gold Base Skin {#pot-of-gold-skin}

The Pot of Gold Base Skin is the flagship cosmetic reward of this event. Based on community reports and early leaks from developer Sammy:

How to get it: Collect and index all limited-time St. Patrick's brainrots

Theme: Full pot-of-gold visual overhaul for your base

Availability: Limited-time only — once the event ends, this skin is gone

This follows the established pattern where completing a mutation's brainrot index unlocks a themed base color. The Pot of Gold skin appears to work similarly but is tied specifically to the St. Patrick's event collection.

This is a limited-time cosmetic. If you want it, you need to collect all eight new brainrots before the event wraps up. Given that six are Secret rarity, start grinding early.

---

Balance Changes {#balance-changes}

Update 42 also brought at least one notable balance change:

Dug Dug Dug income buffed from $255k/s to $35M/s — a massive 137x increase that makes this brainrot significantly more viable for income farming

More balance changes may be discovered as the community digs deeper into the update files.

Tips to Maximize the Event {#tips}

Join servers during Lucky Pot windows — The event triggers every 2 hours with boosted luck. Time your sessions around these windows for the best pull rates.

Prioritize Secret-tier brainrots — Patteo and Clovkur Kurkur (Brainrot Gods) will be the easiest to pull. Focus your energy on landing all six Secrets for the Pot of Gold Base Skin.

Use the Trade Machine — If you pull duplicate Patteos, use the Trade Machine added in last week's Divine Fuse update to trade with other players for the Secrets you're missing.

Don't sleep on the Fuse Machine — The Divine Fuse Machine from Update 41 is still active. If you have four spare brainrots, fuse them for a chance at Divine or Halo variants.

Watch for the Cloverat Clapat spawn — During Lucky Pot events, there's a small chance of this rare NPC appearing. Keep your eyes open.

Complete the collection before the event ends — St. Patrick's brainrots are limited-time. Once the event ends, these characters will no longer be obtainable, making them extremely valuable for trading later.

Check our codes page — While Steal a Brainrot hasn't historically had a code system, the developers may drop surprise codes during major events.

What This Means for the Meta

Two major updates in one week signals that Steal a Brainrot is entering a content sprint. The combination of the Divine Fuse Machine (Update 41) and the St. Patrick's event (Update 42) means:

Trading values for limited brainrots will spike — St. Patrick's brainrots are limited-time, just like previous event characters. Expect them to become premium trade fodder within weeks.

The Dug Dug Dug buff changes income meta — Going from $255k/s to $35M/s makes it one of the best income generators in the game.

Collection completionism is more rewarding — Between the Pot of Gold Base Skin and the mutation-based base colors, there are real cosmetic incentives to collect everything.
