Grow a Garden Guide 2 Ways to Get the Vamp Mutation

The Ghoul Garden Part 3 update in Grow a Garden continues to expand the Halloween festivities with new events, cosmetics, and mutations. Among them is the Vamp Mutation, one of the limited-time Halloween mutations that ties directly into event activities like the Harvest Reaper ritual. If you’ve seen other players’ plants glowing with a dark crimson aura, that’s the Vamp mutation. Here’s a full guide on how to get it, how it works, and whether it’s worth your effort.

What Is the Vamp Mutation?

The Vamp Mutation gives your plants a 3x value multiplier, adding a subtle boost to your earnings while giving them a unique vampire-like look. However, its true importance lies in the Harvest Reaper event, where you’ll occasionally be required to offer plants that carry this specific mutation.

Vamp Mutation Overview:

• Multiplier: 3x
• Obtained From: Bat Attack weather event or Hex Serpent pet
• Event: Halloween (Ghoul Garden updates)

How to Get the Vamp Mutation in Grow a Garden

There are two main ways to obtain the Vamp Mutation: through the Bat Attack weather event or by using the Hex Serpent pet.

1. Bat Attack Weather Event

The Bat Attack weather event doesn’t happen naturally—it must be triggered by players through the Witch’s Brew.

Here’s how it works:

1. Every alternate hour, the Witch NPC spawns at the center of the lobby.
2. You’ll see a large cauldron near her with a progress percentage above it.
3. Players must contribute by submitting harvested plants into the cauldron.
4. Once the cauldron reaches 100%, the Bat Attack event begins and lasts for 5 minutes.

During this event, bats swarm the map, and your plants gain a high chance to receive the Vamp Mutation. Players who contribute to the cauldron also earn Candy Corn, Spooky Eggs, and other rewards.

Tip: Work together with others in your lobby to fill the cauldron faster—this increases the number of Bat Attacks you can trigger within an hour.

2. Hex Serpent Pet

The second way to obtain the Vamp Mutation is through the Hex Serpent, a divine pet introduced in the Ghoul Garden 2 update. You can earn it from the Gravedigging event, which spawns beside the Harvest Reaper every two hours.

Once you have the Hex Serpent, you’ll need to prepare your garden:

1. Purchase the Hex Circle cosmetic from the Devilish Decor shop in the Halloween Market.
2. Place the Hex Circle on your plot.
3. Plant five single-harvest plants inside it.
4. Every 12 minutes, the Hex Serpent performs a ritual, consuming the plants and rewarding you with random Halloween items—and occasionally applying the Vamp Mutation.

Note: The type of plants used doesn’t drastically affect the outcome, so it’s best to use easy-to-grow single-harvest plants to save resources.

Best Tips to Farm the Vamp Mutation

To maximize your Vamp Mutation chances, try these strategies:

• Work in Groups: During the Witch’s Brew period, coordinate with other players to trigger the Bat Attack multiple times per hour.
• Set Up Multiple Hex Circles: If possible, prepare several Hex Circles to let your Hex Serpent perform more rituals.
• Use Cheap Crops: Don’t waste rare plants during the Hex Serpent ritual; common crops yield nearly the same mutation chances.
• Balance Both Methods: Alternate between Witch’s Brew events and Hex Serpent rituals to maintain a steady supply of Vamp-mutated plants.

Is the Vamp Mutation Worth Getting?

Yes—though not for its value multiplier. The 3x multiplier makes Vamp-mutated plants only moderately profitable compared to others. However, the Harvest Reaper event often requires these plants as offerings, making the Vamp Mutation vital for event progression.

If you’re aiming to complete the Reaper’s ritual and unlock exclusive rewards like the Severed Spine, getting the Vamp Mutation is absolutely worth the effort.

The Vamp Mutation in Grow a Garden might not make you rich, but it’s an essential part of the Halloween ecosystem. Whether through the Bat Attack weather event or the Hex Serpent’s ritual, make sure you collect plenty of Vamp-mutated plants before the event ends. They might not sell for much, but when it comes to unlocking limited-time Halloween rewards, they’re worth their weight in Candy Corn.
