Grow a Garden’s Primal Egg Update Adds Spinosaurus, Ankylosaurus & Mutations – Here’s What You Need to Know

[July 13, 2025 | Earthtechy Gaming News Desk]

Roblox’s Grow a Garden just got a prehistoric power-up! If you’ve been itching to add some ancient muscle to your botanical empire, the Pet Mutation Update is your golden ticket. With six new dinosaur pets, the highly-anticipated Primal Egg, and an exciting new way to mutate your companions, this July 2025 update is packed with content that’s worth digging into.

Let me walk you through what’s new—and more importantly—how you can get your hands on the ultra-rare Spinosaurus and other game-changing pets.

🌱 What is the Primal Egg and Why Does It Matter?

The Primal Egg is the crown jewel of this update. Think of it as your gateway to some of the most powerful pets in Grow a Garden, including the elusive Spinosaurus and Ankylosaurus. Whether you’re focused on maximizing crop value, boosting pet XP, or simply defending your fruit from pesky thieves, the Primal Egg pets come with unique traits that offer big in-game advantages.

But here’s the twist—not all Primal Eggs are created equal. You can get them through grinding or spending Robux, and the odds of hatching a top-tier dino vary dramatically. More on that below.

🧪 How to Get the Primal Egg (Both Free and Premium Methods)

There are two main ways to obtain a Primal Egg:

🔹 1. Craft It (Free Method):

If you’re playing free-to-play, your best route is through crafting. First, make sure your DNA Machine is fully upgraded. Then gather these materials:

• 1 Dinosaur Egg
• 1 Bone Blossom crop
• 5.5 million Sheckles

Once you have everything, head to the vendor introduced during the Prehistoric Update, and you’ll be able to exchange your resources for a Primal Egg. It’s definitely a grind, but hey, totally worth it if you’re aiming for the rare drops.

🔸 2. Buy a Premium Primal Egg (Robux Method):

Not up for the grind? There’s a Robux route:

• 1 Egg – 149 Robux
• 3 Eggs – 429 Robux
• 10 Eggs – 1,269 Robux

These Premium Eggs come with a chance to unlock rainbow variants of certain dinos (sadly, not Spinosaurus), and they’re part of a limited-time offer. So if you’re aiming for both power and style, this might be your shot.

🦕 All Primal Egg Pets and Hatch Rates (Spoiler: Spinosaurus is Ultra-Rare)

Now let’s talk odds. The Primal Egg can hatch into one of six pets—each with its own unique trait. But only the lucky few will snag the ultra-rare ones.

Here are the pets and your chances of hatching them:

Pet	Hatch Rate
Parasaurolophus	34%
Iguanodon	32.5%
Pachycephalosaurus	28%
Dilophosaurus	3%
Ankylosaurus	1%
Spinosaurus	0.5%

So yeah, if you’re going after the Spinosaurus, you’re in for a bit of a challenge—but trust me, it’s absolutely worth it.

Primal Egg Pets: Unique Traits That Could Change Your Game

Now, let’s get into what makes each of these new dinosaur pets special. When you hatch a Primal Egg, you’re not just getting a cute companion — each pet offers powerful perks that can seriously boost your garden’s productivity and defense.

• Parasaurolophus: This pet helps by cutting down the wait time for cosmetic crates, especially those with the longest opening durations. Plus, there’s a chance it’ll multiply that time reduction, making it even more effective. If you’re all about aesthetics and efficiency, this one’s a smart pick.
• Iguanodon: This dino gives an experience (XP) boost to all your active dinosaur pets. That means faster leveling and stronger pets overall — a great choice if you want to speed up your progress.
• Pachycephalosaurus: A clever companion that sometimes duplicates your crafted items, giving you more resources without extra work. If crafting is your game, this pet is a definite winner.
• Dilophosaurus: Every 14 minutes, it spits venom that affects three random pets by reducing their cooldown or granting bonus XP. It’s like having a mini team booster constantly helping out.
• Ankylosaurus: Acting as your garden’s bodyguard, this pet gives you a chance to reclaim any fruit stolen by other players. If you’re protective of your harvest (who isn’t?), the Ankylosaurus is invaluable.
• Spinosaurus: The crown jewel! Every 19 minutes, it picks one random fruit mutation from your garden and applies it to another random fruit. This means more opportunities for rare and valuable mutations to spread — perfect for maximizing your garden’s worth.

Between the Spinosaurus and Ankylosaurus, I’d say these two stand out as absolute must-haves if you’re serious about dominating Grow a Garden.

Mutate Your Pets with the New Pet Mutation Station

One of the coolest additions in this update is the Pet Mutation Station. It lets you evolve your pets beyond their standard forms by applying mutations — think of it like giving your dinosaurs a power-up that changes their stats, appearance, and abilities.

Here’s the deal: only pets at level 50 or higher can be mutated, and there are 12 different mutations to discover. Each mutation gives your pets unique traits that can dramatically impact gameplay. Want your Iguanodon to be even better at XP boosts? Or your Ankylosaurus to offer more protection? This system lets you customize your strategy.

You’ll find the Mutation Station next to the Pet Eggs stand — a quick visit there could be the difference between a good pet and a game-changing companion.

New Events to Keep Things Fresh

The lead-up to this update also brought some exciting events. Remember the Brains.. event? Zombies sprinted to players’ gardens infecting plants with the new Infected mutation — adding an extra layer of challenge and fun.

There’s also the Pool Party! event, mainly cosmetic but a great way to grab the exclusive Duckfloat skin. You’ll find a pool with slides and diving boards near the Gear Stall, perfect for relaxing after all that gardening.

And for fans of obbies, a new sky obstacle course popped up, offering the chance to unlock the coveted Jump Pad cosmetic. You can even complete it multiple times to stack those rewards.

These events add personality and variety, keeping Grow a Garden exciting beyond the core gameplay.

Gear Up with New Items to Level Pets Faster

Leveling pets to 50 for mutations can take time, but the update introduces some handy new gear to speed things up. Some of these are craftable, while others appear in the Gear Shop:

• Small and Medium Toys and Treats, which give your pets a boost in experience gain.
• The Level Up Lollipop is especially helpful, giving a significant XP surge to get your pets mutation-ready faster.

Investing in these items is smart if you want to maximize your pet’s potential without grinding endlessly.
