Plants vs Brainrots is celebrating St. Patrick's Day with a limited-time event running from March 14 to March 21, 2026. This one works differently from past events, instead of farming currencies, you're submitting gold-mutated plants and brainrots to work through 50 reward tiers. This guide covers everything you need to know about Plants vs Brainrots St. Patrick’s Day event to make the most of it before time runs out.

What is the St. Patrick's Day Event in Plants vs Brainrots

The St. Patrick's Day Event is a limited-time event you can access through the Central Island. The event POI is a giant gold pot sitting in front of a rainbow. To the left of the pot, you'll find the event NPC, which is where all the action happens.

The whole event is built around submitting Gold Mutated plants or brainrots to the NPC. But there are two rules you need to know before you start submitting:

  • The plant or brainrot you submit must have the Gold Mutation. No other mutations count on their own.
  • Gold mutated brainrots from eggs won't work. Only those you've raised yourself are accepted.

Double mutations are totally fine, too. A gold frozen plant or a gold rainbow brainrot? Both work, as long as gold is one of the mutations.

All Plants vs Brainrots St. Patrick's Day Event Rewards

The event has 50 tiers of rewards, and each submission you make clears one tier. As you progress, you'll pick up a mix of plants, brainrots, cash, card packs, EXP gears, and potions along the way. Once you clear all 50 tiers, you get three exclusive rewards:

  • 1x Swag Clovelloni
  • 1x Biggify Potion
  • 1x Pot of Gold Seed

You can reset the event with in-game cash and run through it again to collect duplicate rewards before March 21st, 2026.

How to Complete the St. Patrick's Day Event

The strategy here is simple: submit gold-mutated plants and brainrots as fast as you can. Here's how to do it efficiently:

  1. Go to the Central Island and look for the giant gold pot with a rainbow. Walk up to the event NPC on the left to open the submission menu.
  2. Submit any plant or brainrot with a Gold Mutation to clear a tier. You don't need a specific plant. Any gold-mutated one works.
  3. For the fastest progress, use common plants like Cactus or common brainrots like Noobini Bananini. They're easier to get in bulk and work just as well as the rare ones.
  4. Keep submitting until you clear all 50 tiers and grab your three final rewards.
  5. If you want more rewards, spend some in-game cash to reset the event and go again.

This event is actually a great time to put all those unwanted gold mutations to use. Good luck and wish you a shamrocking good time!
