How to Start and Activate the SNOWMAN UPDATE
To begin the SNOWMAN UPDATE in Plants Vs Brainrots, you need to go to the marked location on the map and talk to the snowman NPC. After the conversation, the event will start. The NPC will give you a backpack with 250 empty slots, and your task will be to collect Snowballs.
In total, you need to gather 5000 Snowballs to complete your snowman and receive the final reward of the SNOWMAN UPDATE.
Note: To see and play this event, your game must be updated to the latest version. Otherwise, you won't have access to it. You can also use VIP servers if you prefer.
How to Collect Snowballs?
There is only one way to get Snowballs in the SNOWMAN UPDATE: by killing Brainrots that have Snow mutations. Defeating them will give you one Snowball. The rarer the Brainrot with this mutation, the higher your chance of getting more Snowballs at once—typically between 5 to 10.

Snowballs are automatically added to your backpack no matter where you are. You don't need to be in a specific area to pick them up.
How to Collect and Turn in Snowballs AFK in SNOWMAN UPDATE
The best method to complete this event while AFK is to use a macro or any auto-clicker tool. Stand next to the snowman NPC and set your macro to press and hold the E key every few minutes. This will automatically empty your backpack at regular intervals. This way, you can finish the SNOWMAN UPDATE quickly without worrying about your backpack filling up while you're away.
SNOWMAN Event Rewards
By progressing through the event, you'll earn various great rewards. Here’s what you can get:
250 Snowballs: You receive an Expansion Card Pack.
700 Snowballs: You earn an XP Bottle.
Over 1,000 Snowballs: Rewards like Christmas Eggs become available, which are valuable for the rest of the event.
The final reward for collecting 5000 Snowballs and completing the event is the Gran Snomancello. This item is especially valuable because it is a new Plant.

Does the Event End After Completing It Once?
No, it doesn't. After fully collecting 5000 Snowballs, you can click the "Claim and Restart" button to activate the event again. You can repeat it as many times as you want.
How to Increase Your Snowball Collection Speed
To collect Snowballs faster and progress more quickly, it's important to use a potion—but which one?
Since you get Snowballs by killing rare Brainrots with Snow mutations, you should use a Rarity Potion.
This potion increases the spawn rate of rare Brainrots, and these will have the Snow mutation. You can imagine the result.
I can confidently say this is the best and fastest strategy. You can easily complete the SNOWMAN UPDATE in Plants Vs Brainrots at maximum speed and earn plenty of rewards as long as the event is active. Don't waste time—start now.
