The Ice Boss Event is one of the biggest limited-time server events added to Plants Vs Brainrots, which added a large-scale co-op gameplay to the forefront. Instead of grinding solo content, in this event, you need to work together using Snowballs to take down a powerful seasonal boss. Centered around King Krakolemi, the Ice Boss Event has tons of time-limited reward shops. So, to help you beat this boss and get all the rewards, here's a complete Ice Boss Event guide for Plants vs Brainrots.
How to Start Ice Boss Event in Plants Vs Brainrots

To begin the Ice Boss Event, you must travel to Central Island, which unlocks once you reach Rebirth 1 and pay 1,000,000 Cash to access the area. As soon as you arrive, an NPC named Icebarrello Pirati introduces the event mechanics and explains how the Ice Boss encounter works.
Once the event starts, King Krakolemi spawns on the island alongside a massive cannon. This cannon is the only way to damage the boss, and it runs entirely on Snowballs. Since this is a server-wide event, everyone in the server contributes to defeating the boss together.

King Krakolemi has 1,000 HP and is the first server-boss of its kind. Each cannon shot that you fire consumes 125 Snowballs and deals 50 damage, meaning a full kill requires 20 successful shots.
Because Snowballs are shared effort-wise, you will get many more rewards for being on an active server or private server. Once the boss is defeated, you get two types of rewards. A limited-time shop spawns that opens for five minutes, and milestone rewards are granted based on how many shots you personally contributed.
How to Get Snowballs in Ice Boss Event
Snowballs are obtained by defeating Brainrots with the Snowy Mutation. These spawn naturally from the conveyor during the Christmas update. The amount of Snowballs dropped scales with the Brainrot’s size and HP.
Smaller Snowy Brainrots usually drop between 10 and 25 Snowballs, while stronger variants can drop much more. For example, I defeated a Snowy Brainrot with over 5 million HP, which rewarded me 110 Snowballs in a single kill. So, farming higher-tier Snowy Brainrots is the fastest way to fuel the cannon.
All Ice Boss Event Rewards

Unlike previous Christmas events, the Ice Boss event has many more rewards for you to earn. Specifically, you can get rewards from two places: the Limited Shop that spawns after beating the Boss, and the second is the Milestone rewards for damaging the Boss. Here are all the rewards you can get from each of these places:
Ice Boss Limited-Time Shop Rewards
After defeating King Krakolemi, a special shop appears for five minutes. These items are purchased with Cash and include seasonal exclusives.
| Item | Cost |
|---|---|
| Winter Rose Seed | $100,000,000 |
| Rocket Button Gear | $10,000,000 |
| Christmas Card Pack | $10,000,000 |
| Hot Cocoa Decoration | $5,000,000 |
The Rocket Button Gear is especially valuable, targeting a single Brainrot and dealing around 1 million damage per shot, with four total uses.
Ice Boss Milestone Rewards
Milestone rewards are granted based on how many cannon shots you personally fire at the boss. These rewards can be reset for $10,000,000 Cash, allowing you to earn duplicates.

Frequently Asked Questions (FAQs)
No. The event is server-based, and progress is much faster when multiple players contribute Snowballs and cannon shots together.
The boss requires 20 cannon hits, and each hit costs 125 Snowballs, totaling 2,500 Snowballs per full kill.
The Frostalo Berrino Seed and Rocket Button Gear are considered the most valuable, especially for making a strong late-game team and getting higher DPS for your lanes.
