The Ghoul Garden Halloween Event in Grow a Garden has introduced one of the most profitable mechanics in the game — the Ghostly Mutation. This limited-time feature can increase the selling price of your crops by up to 28× their base value, turning even ordinary plants into massive money-makers. Here’s a complete guide on what the Ghostly Mutation is, how to get it, and whether it’s worth the investment.
What Is the Ghostly Mutation?
The Ghostly Mutation is a special Halloween-exclusive mutation that transforms your crops into semi-transparent plants surrounded by haunting ghostly particles. But the visual change is just the beginning — the real value lies in its incredible 28× sell price multiplier. This means even a low-value crop can instantly become one of your most profitable harvests once affected by this mutation.
How to Get the Ghostly Mutation
There are two main ways to unlock Ghostly Mutation effects in your garden during the Ghoul Garden Event:
1. Using the Great Pumpkin Seed
The Great Pumpkin is a Transcendent-type crop that can automatically apply Ghostly Mutation to other plants. You can buy it during the event at Sam’s Seed Shop for 15 billion Sheckles or 1,199 Robux. Once planted, the Great Pumpkin will grant Ghostly Mutation to one random crop every 5 minutes, completely automatically. You don’t need to do anything — it continuously spreads the effect while it’s active. This is the most efficient and reliable method to obtain Ghostly Mutation since the process is consistent and doesn’t rely on RNG.
2. Using Ghostly Mutated Pets (From Premium Spooky Eggs)
Another method is through Ghostly Mutated Pets, which can be hatched from Premium Spooky Eggs. These special pets have a 1% chance to apply the Ghostly Mutation effect to your plants. There’s also a pity system, guaranteeing one Ghostly Pet after 125 Premium Spooky Eggs. Here’s the pricing breakdown for Premium Spooky Eggs:
- 1 pack – 149 Robux
- 3 pack – 429 Robux
- 10 pack – 1,249 Robux
To reach the 125-egg guarantee, you’d need around 15,625 Robux, which makes this method much more expensive than the Great Pumpkin route. While it’s a fun and collectible option for dedicated players, it’s not the most cost-efficient path to Ghostly Mutation.
Is the Ghostly Mutation Worth It?
- Absolutely — especially for late-game players.
The Ghostly Mutation can dramatically boost your income with its 28× price multiplier, making it one of the most lucrative features ever introduced in Grow a Garden. If you use the Great Pumpkin, you’ll passively generate a new Ghostly Mutated crop every 5 minutes, allowing your profit to scale steadily over time.
While the 15 billion Sheckles / 1,199 Robux price tag might seem steep, the return on investment is fast — especially if you’re growing Transcendent or Prismatic-tier crops.
On the other hand, the Ghostly Pet route is more of a luxury choice. It’s expensive, unpredictable, and mainly suited for collectors who want every event-exclusive item.
The Ghostly Mutation is easily one of the most rewarding systems ever added to Grow a Garden. During the Ghoul Garden Halloween Event, it can multiply your crop value by up to 28×, transforming your garden into a powerhouse of profits. If you want guaranteed results, go for the Great Pumpkin — it’s consistent, passive, and far more affordable than hatching dozens of Premium Spooky Eggs.
But if you enjoy the thrill of rare drops and want something exclusive, the Ghostly Pet method can still be a fun challenge. Whichever path you choose, don’t miss out — the Ghostly Mutation is a limited-time feature, and once the Halloween event ends, it may not return for a long time.
