In the ever-evolving world of Grow a Garden, new pets constantly reshape the game’s balance, economy, and strategies. But among the latest additions, few creatures have caused as much excitement—and chaos—as the Huge Nightmare Mimic Octopus. Weighing an astonishing 61.25 kilograms, this mutated leviathan stands as one of the most powerful and complex pets in the entire game. Even more impressive? It was created by the Rainbow Elephant, the only creature in the game capable of producing pets of such massive size and rarity.
In this guide, we’ll explore every aspect of the Huge Mimic Octopus—from its unique copy ability and cooldown mechanics, to its best pet combos, Roblox Grow a Garden Items, and current trade market value. Whether you’re a veteran collector or a strategic gardener aiming to optimize your lineup, this breakdown will show why the Huge Mimic Octopus is a true game-changer in Grow a Garden.
Origins of the Huge Mimic Octopus
Before diving into the gameplay aspects, it’s worth noting just how extraordinary this creature is. The Rainbow Elephant—a mythical pet with an extremely low hatch rate (about 1 in 10,000)—is the only source capable of producing a Huge Mimic Octopus of this size. The base weight of Rainbow Elephant-created pets starts around 6.1 kg, allowing mutations and growth that push them far beyond the limits of normal breeding.
The result? A 61.25 kg nightmare mutation mimic octopus, the heaviest ever recorded in-game at the time of writing. It’s not only a spectacle to look at but also the strongest utility pet when used strategically.
Skill Overview – Copying Like No Other
The Mimic Octopus has one of the most innovative skills in Grow a Garden: the ability to copy another pet’s ability within your garden at fixed intervals, cheap Roblox Grow a Garden Items.
Base Cooldown: 20 minutes (standard mimic)
Cooldown at 61 kg (nightmare mutation): 15 seconds (cap)
Cooldown with Medium Toy: Reaches hard cap consistently at 15 seconds
This cooldown scaling is what makes the Huge Mimic Octopus so dangerous. By increasing its weight and mutation rarity, the cooldown shrinks dramatically, allowing the player to chain-copy abilities at near-continuous rates.
However, not all pets can be copied. These include:
Hydra
Green Bean
Sugar Glider
Chinchilla
Rhino
Elephant
Imp
Red Panda
French Fry Ferret
And, as a rule, pets with no cooldown-based abilities are also excluded.
That might sound restrictive, but here’s the genius part:
The Mimic Octopus copies abilities based on its own stats, not the original pet’s stats.
So, if you have a 20 kg rainbow mutation mimic octopus and it copies a 10 kg pet’s skill, the resulting ability scales off the octopus’s higher weight and rarity. This means a Huge Mimic Octopus isn’t just mimicking—it’s enhancing every skill it copies.
Essentially, owning one is like having every pet in the game compressed into a single slot.
Real Performance Tests
Test #1: Fastest Egg Hatching
For this test, we used:
Six Bald Eagles
One 61 kg Mimic Octopus
One 39 kg Mimic Octopus
Medium toys for cooldown cap
Each skill activation from the octopus shortened hatching time by about 15 minutes. When used on 13 Paradise Eggs (each normally taking 6 hours 40 minutes to hatch), the total hatch time was reduced to just 10 minutes.
That’s not just efficient—it’s game-breaking. For shorter-duration eggs (around 4 hours), the hatch time was nearly cut in half. Players aiming to mass-produce rare pets or chase mutation variants can save dozens of hours every week using this setup.
Test #2: Fast Leveling Combo
Next, we tested how effectively the Huge Mimic Octopus could accelerate pet leveling.
Setup:
Multiple French Fry Ferrets
One Peacock
Optional: Rainbow Dilophosaurus
In this configuration, the mimic copies the Peacock’s cooldown reduction ability, which boosts the Ferrets’ level-up frequency. When a Rainbow Dilophosaurus is added, the entire leveling rate doubles.
The result?
A pet can reach Level 100 in just 20 minutes.
For reference, normal progression takes over two hours without boosts. This combo is perfect for new gardens looking to power-level multiple pets without relying on rare consumables or expensive mutation machines.
Test #3: Rapid Nightmare Mutations
Before the release of the Headless Horseman, players relied heavily on the Mutation Machine. Now, that’s no longer necessary.
The Headless Horseman provides:
22% passive mutation boost
12% nightmare mutation rate (giant version)
Level 30 requirement
By copying the Horseman’s ability, the Huge Mimic Octopus can massively accelerate mutation rates. When used in sync with medium toys and high mutation synergy pets, nightmare mutations appear at record speed—making it one of the most efficient mutation farming methods currently available.
Advanced Combos and Synergies
While the previous setups show the octopus’s raw power, its true potential comes from creative synergy.
1. Mutation Boosting
Pair the Huge Mimic Octopus with pets like:
Disco Butterfly
Mutant Beetle
Each of these pets boosts mutation frequency or rarity. When the mimic copies one of these abilities, you get mutations every 15 seconds or faster.
2. Web Acceleration Combo
Place the mimic inside a Giant Spider’s web area. The spider’s passive web aura further reduces cooldowns, sometimes allowing the mimic to trigger every 6 seconds.
Note: Occasionally, the mimic may copy the spider’s web skill instead, but even then, the resulting frequency makes up for it.
3. Balanced Utility Setup
If you want a general-purpose garden setup:
Huge Mimic Octopus (Rainbow Mutation)
Titan Peacock (Cooldown Reduction)
Bald Eagle (Egg Hatching)
Headless Horseman (Mutation Boost)
Rainbow Dilophosaurus (XP Boost)
This combination covers every major system—egg production, leveling, and mutation—while keeping cooldowns constantly cycling.
Trade Value and Market Analysis
Before Rainbow Elephant Update
Before the Rainbow Elephant entered the game, Huge Mimic Octopuses were almost mythical. An 80 kg octopus could easily sell for $1,000 USD or the equivalent of 12 Kitsunes in in-game trade value. The scarcity made it nearly impossible for average players to obtain one.
After Rainbow Elephant Release
Once the Rainbow Elephant was introduced, everything changed. Players could now create heavy pets like the Huge Mimic Octopus directly, skyrocketing supply and dropping prices dramatically.
Currently:
61 kg Huge Mimic Octopus: ~5–6 Kitsunes
80 kg version: still rare, but not worth more than 1 Rainbow Elephant
While the 80 kg version is technically stronger, the performance gap between 60 kg and 80 kg versions is negligible once both use medium toys. Thus, paying extra for a heavier one is not recommended.
Smart traders now prefer keeping their Rainbow Elephant, as its value keeps rising due to rarity, while Mimic Octopus prices continue to fall.
If you already have a normal Elephant, you can still upgrade a smaller Mimic Octopus into a powerful one. Our 39 kg nightmare mutation octopus was created this way and still performs incredibly well. Visually, it also carries the distinct glowing pattern that marks nightmare mutations—a fan-favorite cosmetic.
Why the Huge Mimic Octopus is a Game-Changer
In Grow a Garden, progression is often limited by timers—egg hatching, leveling, and mutation. The Huge Mimic Octopus effectively breaks those limits by accelerating every one of those systems simultaneously.
It’s not just a power pet—it’s a time machine for your garden. Whether you’re grinding for rare mutations, preparing for competitive leaderboard seasons, or just optimizing your pet setup, this creature is a one-stop solution.
Its flexibility is unmatched:
Want faster eggs? Copy a Bald Eagle.
Need quick leveling? Copy a Peacock.
Want more mutations? Copy a Headless Horseman.
Every 15 seconds, the Huge Mimic Octopus becomes a different tool. No other pet in the game comes close to that versatility.
The Future of Pet Meta
The arrival of the Rainbow Elephant and Mimic Octopus synergy has reshaped the Grow a Garden meta. Players are now building entire gardens around cooldown loops, where one pet reduces another’s cooldown, and the mimic copies that ability endlessly. This could push future updates toward cooldown balancing or even new anti-loop mechanics.
Until then, the Huge Mimic Octopus remains one of the strongest investments you can make—especially for those who enjoy discovering efficient combinations and dominating trade markets.
Conclusion
The Huge Nightmare Mimic Octopus is not just another rare pet—it’s the ultimate meta-defining powerhouse of Grow a Garden. Its unmatched versatility, ability to copy and enhance abilities, and synergy with core pets like the Headless Horseman and Rainbow Dilophosaurus make it an essential tool for serious players.
Whether you’re chasing mutations, grinding XP, or building an efficient farm setup, this colossal creature will turn your garden into a powerhouse of production and progression. Just remember: in Grow a Garden, the smartest players don’t just grow plants—they grow power. And nothing embodies that power quite like the Huge Mimic Octopus.
