The latest update in Roblox’s Grow A Garden introduces an exciting Prehistoric event, showcasing a new mutation for avid gardeners: the Old Amber Mutation.
Completing the Prehistoric event wouldn’t be the same without the formidable Amber mutation, now featuring three distinct variations for players to pursue.
If you’re looking to enhance your garden with prehistoric flair, let’s explore how to unlock each mutation type and the significant benefits they can provide.
1. How to Obtain the Amber Mutation in Grow a Garden Roblox?

The Amber mutation, launched with the Prehistoric update, stands as one of the game’s most robust crop enhancements. Players can unlock it through two main methods: using the Raptor dinosaur pet or crafting an item known as the Amber Mutation Spray.
Crops with the Amber mutation will be highlighted with a dark yellow outline, varying in shape depending on the type and size of the crop. This mutation yields an impressive profit boost, applying a tenfold multiplier to the affected crops.
i. Unlocking the Base Amber Mutation Using the Raptor Pet

The Raptor dinosaur pet grants a subtle chance (approximately 2%) for crops to gain the Amber Mutation upon harvest. Raptors can be obtained from Dinosaur Eggs, which are acquired in various ways during this event:
- Chat with Graham at the event shop located in the center of the map to craft Dinosaur Eggs.
- Donate unwanted pets to activate the DNA chamber and wait for an hour for the crafting process to complete.
- Utilizing rarer pets increases the chances of hatching a dinosaur.
- Complete event quests to earn additional Dinosaur Eggs.
- Consult Blaire in the event shop to monitor daily and weekly quests.
- Fulfill these tasks for extra rewards, including Dinosaur Eggs.
Hatching a Dinosaur Egg takes approximately 4 hours and 10 minutes, with a 35% chance of producing the Raptor, making it a common choice among dinosaur pets.
The Raptor provides two passive features:
- Clever Claws: Offers a 2%–2.5% chance for fruit to obtain the Amber mutation during harvesting (lower odds for rarer plants).
- Raptor Dance: Grants a movement speed boost of 14%–14.5% to your character.
ii. Unlocking the Base Amber Mutation Using the Amber Mutation Spray

If you prefer a more direct approach, the Amber Mutation Spray allows you to apply the Amber Mutation to any suitable crop instantly.
While obtaining the Amber Mutation Spray is the most effective method for ensuring an Amber mutation, it does require a considerable investment. Here’s what you’ll need to craft it:
- 1x Cleaning Spray – Available for purchase from the Gear Shop for 15 million Sheckles, this is the most costly and rare ingredient.
- 1x Dinosaur Egg – As mentioned, obtainable via Graham or through event quests.
- 1 million Sheckles – Required as part of your crafting expenses.
Once you have gathered the necessary materials, navigate to the Prehistoric crafting station located at the center of the map, and follow these instructions:
- Interact with the gear crafting station next to Blaire NPC by pressing E.
- Select the Amber Mutation Spray from the recipe list.
- Press the Craft button and confirm your ingredient submission by pressing E again.
- Wait for 60 minutes for the crafting to complete, or opt to spend 39 Robux to bypass this time.
- Once ready, press E to collect your spray, which will be added to your backpack automatically.
You can also earn the Amber Mutation Spray as a reward for completing Prehistoric quests or via the weekly prize pool.
| Effect | Instantly applies the Amber mutation to a crop |
| Usage | Single-use per spray |
To utilize the spray, simply open your inventory, equip the spray, and click on the crop you wish to mutate. If the crop meets the requirements, the Amber mutation will be applied immediately. If not, you will be prompted to select a different crop.
iii. Best Approach to Achieve the Amber Mutation

Given that the Raptor’s chance of applying the mutation is relatively low at around 2–2.5%, the Amber Mutation Spray offers a guaranteed method to achieve this valuable crop enhancement.
To optimize both your mutation chances and profits, it’s advisable to employ a dual strategy: make the most of the Raptor’s passive ability while crafting sprays whenever possible. This combined approach helps ensure you maximize on mutations and stay competitive within the event.
Additionally, crafting the Amber Mutation Spray aids in completing Prehistoric quests that call for gear crafting, enhancing your weekly prize progression and increasing the potential for obtaining rare items such as the Bone Blossom. So, if crafting the spray aligns with your current quests, it’s definitely worthwhile.
By effectively utilizing both the passive ability of the Raptor pet and the crafting of sprays, you can enhance your overall efficiency and maximize the rewards from the event.
2. How to Retrieve Old Amber and Ancient Amber Mutations in Grow a Garden Roblox?

Once you possess a crop with the Amber mutation, you can evolve it over time into even more lucrative versions:
- Old Amber (x20 Multiplier) – After 24 hours, any crop with the base Amber mutation will automatically transform into Old Amber, effectively doubling its multiplier to x20.
- Ancient Amber (x50 Multiplier) – With additional time, Old Amber will further evolve into Ancient Amber, offering a staggering multiplier of x50.
- Avoid harvesting crops prematurely if your goal is to achieve the higher-tier mutations.
- Favor your mutated crops to prevent unintended harvesting.
- Monitor their aging process closely and consider combining Ancient Amber with other rare mutations to maximize their value significantly.
Whether you’re utilizing the Raptor’s passive abilities or investing in Amber Mutation Sprays, the Old Amber Mutation is a potent asset within Roblox Grow A Garden.
Harness its potential to amplify your harvest and expedite your progress through the Prehistoric event!
