The Vamp Mutation is one of the spookiest and most popular features introduced in the Grow a Garden Halloween event.
This special mutation gives your plants a 3x value multiplier and is required for the Harvest Reaper Event, making it both fun and valuable to collect.
In this guide, we’ll walk you through all the ways to get the Vamp mutation, how the Bat Attack event works, and how to use your Hex Serpent Pet to create this rare effect in your garden.
What is the Vamp Mutation?
The Vamp Mutation gives your crops a glowing red aura and triples their base value.
Besides looking visually stunning, it plays a crucial role in event-based quests like the Harvest Reaper, where you’ll need to submit plants with this exact mutation.

How to Get Vamp Mutation in Grow a Garden
There are two main methods to obtain the Vamp Mutation in Grow a Garden:
-
During the Bat Attack Weather Event
-
Using the Hex Serpent Pet Ritual
Let’s break down both methods in detail.
Method 1: Bat Attack Weather Event
The Bat Attack is a limited-time weather event that turns the sky red and releases a swarm of bats over your garden. During this short period, every plant in your garden has a chance to gain the Vamp mutation.
How to Trigger the Bat Attack:
-
Head to the Witch’s Cauldron located at the center of the lobby.
-
During the Witch’s hour (appears every alternate hour), players can contribute harvested fruits and items into her cauldron.
-
Each contribution increases the percentage meter above the cauldron.
-
Once the bar reaches 100%, the Bat Attack event will automatically start and last for about 5 minutes.
What Happens During Bat Attack:
-
The entire map darkens with red lighting.
-
Bats fly across the sky.
-
Any active fruit in your garden has a high chance of receiving the Vamp Mutation.
-
You’ll also earn Candy Corns and Spooky Eggs for your contributions.
Tip: The event requires collective effort. Join an active server where players are contributing to the cauldron consistently to trigger the Bat Attack faster.
Method 2: Hex Serpent Pet Ritual
The second way to get Vamp Mutation is through the Hex Serpent, a divine pet introduced in the Ghoul Garden 2 update.
How to Obtain the Hex Serpent:
-
You can earn this pet from the Gravedigging Event, which appears every 2 hours beside the Harvest Reaper NPC.
-
The Hex Serpent has a low drop chance, so you’ll need a bit of luck to get it.
How the Ritual Works:
Once you have the Hex Serpent pet, you’ll need a Hex Circle cosmetic, which you can purchase from the Devilish Décor shop in the Halloween Market.
-
Place the Hex Circle in your garden.
-
Plant 5 single-harvest plants inside the circle.
-
Every 11.53 minutes, the Hex Serpent performs a ritual — it consumes the plants, triggering random Halloween effects, including the Vamp Mutation.
-
The rarer your plants, the stronger your potential rewards.
Pro Tip: Use cheap, single-harvest plants for faster results since rarity doesn’t guarantee Vamp Mutation but affects secondary rewards.
Best Tips to Increase Vamp Mutation Chances
-
Team Up for the Witch’s Brew: Join active servers where multiple players contribute to the Witch’s Cauldron. The faster it reaches 100%, the more frequently you’ll experience the Bat Attack.
-
Use Single-Harvest Plants for Rituals: While higher rarity plants can give better bonuses, using quick-grow plants lets you attempt more Hex Serpent rituals in less time.
-
Switch Between Methods: Use both Bat Attack and Hex Serpent methods to boost your overall mutation chances.

Is the Vamp Mutation Worth It?
Definitely, yes – but mostly for event progression rather than profit.
While the 3x multiplier doesn’t drastically increase your overall income, Vamp Mutations are essential for quests like the Harvest Reaper, where you must turn in specific mutated crops.
If you’re chasing full completion for Halloween achievements or exclusive items, the Vamp Mutation is a must-have.
Summary Table
| Method | How It Works | Duration | Best For |
|---|---|---|---|
| Bat Attack Event | Contribute to Witch’s Cauldron until it reaches 100% to trigger the event | 5 minutes | Quick, mass mutation |
| Hex Serpent Ritual | Pet consumes plants every 11.53 min inside a Hex Circle | Continuous | Passive farming & exclusive rewards |
Final Thoughts
The Vamp Mutation is one of the best Halloween-exclusive features in Grow a Garden.
Whether you get it through the Bat Attack or your Hex Serpent, it adds both flair and function to your plants. Even though it’s not the most profitable mutation, it’s essential for completing special events like the Harvest Reaper Quest.
So, light up your Hex Circle, fill that cauldron, and get ready to harvest some vampiric fruits before the bats vanish for the season.
