Something special just dropped in your favorite Roblox game! The game added a new Christmas event where you can build Santa’s Platform in Plants vs Brainrots using a plant called Sir Whiskerwood. It’s all about defeating special holiday Brainrots and growing plants in your garden. Let me break down exactly how this works so you can start earning those rewards.

How to Get Sir Whiskerwood Seeds in Plants vs Brainrots
The Biome Totem just unlocked something cool in Santa’s Arrival update. You can now access Santa’s Workshop, which is a special Christmas-themed biome. In this biome, Santa’s Workshop spawns unique Christmas Brainrots that you will not find anywhere else in the game. These special Brainrots are part of the holiday event, so you’ll want to take advantage of them while they’re available. They’re your ticket to getting the materials you need for building Santa’s Platform.
When you defeat Christmas Brainrots inside Santa’s Workshop Biome, you earn Sir Whiskerwood Seeds as rewards. You can use these seeds to grow Sir Whiskerwood plants in your garden. So the first few steps are:
- Visit Santa’s Workshop using the totem in your garden
- Let your plants fight the Christmas Brainrots, and you will collect the Whiskerwood Seeds automatically after each battle.
- Once you’ve got your Seeds, head over to your garden and plant these seeds.



Now comes the waiting part. You need to let Sir Whiskerwood grow completely before you do anything else. When your Sir Whiskerwood is fully grown, grab your shovel. You’ll need to shovel out the grown plants from your garden. This is an important step because you can’t submit the plant until you dig it up first.
How to Build Santa’s Platform in Plants vs Brainrots
After you shovel out your grown Sir Whiskerwood, you need to submit it. Go to the Central Island, and find a machine where you can submit plant Whiskerwood to progress in building Santa’s Platform. You will get rewards every single time you submit a plant.

This means you’re not just working toward one big reward at the end. Every Whiskerwood you submit counts and gives you something in return. The more plants you grow and submit, the faster you’ll build Santa’s Platform and rack up those rewards. Here are the rewards for each platform you build:
