If you've been playing Grow a Garden for a while, you know that leveling up your pets can be both fun and a bit overwhelming. One of the most exciting challenges in the game is turning your Mimic Octopus from a small, standard pet into a colossal, Titanic-level companion. After testing the latest techniques, I wanted to share a detailed walkthrough that not only explains the process but also highlights some tips that might save you time and effort.

From Small to Huge: The Basics

The first stage in upgrading a Mimic Octopus is growing it from a small size to a huge one. In my experience, the key is using the Rainbow Hatch method. I personally combined my Rainbow Hatch Dilo with other pets like the Spider and Peacock to maximize growth efficiency. Once you have all eight slots filled, you simply wait—typically around 2–3 hours AFK—and watch your Mimic Octopus reach around 60 kilograms.

The transition from small to huge might seem straightforward, but patience is essential. One tip I’ve found helpful is keeping an eye on the cooldowns for each pet’s skill. This creates a domino effect, speeding up the growth if timed correctly. It’s a little fiddly at first, but once you get the rhythm, it becomes a smooth process.

Achieving Nightmare Mutation

After reaching the huge stage, the next goal is the Nightmare Mutation. For this, you’ll need a combination of specific pets, including the Dilo, Headless Horseman, Spider, and a Cleaning Pet Shard. The goal here is to create a continuous cycle where your Mimic Octopus gradually evolves into its mutated form.

I was lucky enough to get the Nightmare Mutation on the second try. But even if you don’t, remember that patience and proper setup are key. Once your Mimic reaches this mutation, it’s much closer to the coveted Titanic form.

If you’re eager to enhance your pet collection beyond the usual gameplay, you might consider options to buy grow a garden pets. This can help fill gaps in your collection and speed up processes like these, especially if you want access to rare or high-tier pets quickly.

Turning Huge Mimic into Titanic

The final stage is transforming your huge or mutated Mimic Octopus into a Titanic pet using the Pet Age Breaker machine. Here, preparation is crucial. You’ll need 25 smaller Mimics ready as sacrifices for the machine. Once submitted, you have the choice to either wait for the natural cooldown or use Robux to skip the process. In my run, spending around 1,250 Robux allowed me to reach a 75-kilogram Titanic Mimic with an impressive 38-second cooldown, which is extremely efficient in practical gameplay.

A neat tip: always double-check that you’re not accidentally submitting your favorite or god-tier pets to the machine. The system prevents submitting favorites, but it’s easy to forget in the heat of gameplay.

For players who don’t want to go through hours of AFK waiting, you can also buy grow a garden pets from U4GM. This service allows you to access rare and high-level pets directly, which can save considerable time while still being a legitimate way to strengthen your roster.

Practical Advice and Time Investment

While the process is exciting, it’s worth considering the time and resources involved. Transforming a Mimic Octopus to Titanic level can take 37–40 hours of active management if you’re continuously feeding it into the Pet Age Breaker. That said, the investment pays off if you plan to trade or showcase your pet, as Titanic Mimics are highly desirable in the community.

One thing to remember: the in-game market can fluctuate, so the value of a Titanic Mimic may not always be stable. If you plan to trade, keep an eye on market trends and think strategically about timing.

Turning a Mimic Octopus from small to Titanic is a multi-step journey that requires careful planning, patience, and strategic use of in-game mechanics. From growing it huge with Rainbow Hatch methods to achieving Nightmare Mutation, and finally using the Pet Age Breaker machine, each stage has its nuances. Players who are willing to invest the time—and optionally consider services like U4GM to acquire pets—can see significant rewards, both in gameplay efficiency and trading potential.
