Leveling pets efficiently is one of the core progression systems in Grow a Garden, and mastering it can dramatically boost your farming speed, resource gains, and overall gameplay experience. Whether you're a new player trying to reach your first milestone or a veteran optimizing dozens of pets at once, understanding which setups deliver the highest XP per second is absolutely essential.

In today’s deep dive, we break down the fastest level 0 to 30 pet-leveling combos currently available in the game. Every combo listed here has been tested in real gameplay, with full timing, resource requirements, Grow a Garden Items, disadvantages, and overall practicality considered. You’ll be able to see how your own setup compares—and maybe discover a new optimization you haven’t tried yet.

But before we jump into the hardcore testing results, there was a fun surprise shown at the beginning of our test run: a 72 kg Giant Bean Raptor pet giveaway. Not only does it look hilariously oversized, but it’s also one of the most eye-catching support pets in the entire game. The entry is simple, so if that giveaway is still active, it might be worth checking out.

With that out of the way, let’s get straight into the rankings.

Combo 1: Golden Piggy + Six Ruby Squids

Time from Level 0 → 30: ~16 minutes

XP Per Second: ~735 XP/s

Difficulty: Moderate (requires crafted gold ingots)

The first combo on our list is one many players are already familiar with: one Golden Piggy paired with six Ruby Squids. Despite how simple it looks on paper, this setup is surprisingly powerful, consistent, and beginner-friendly.

Why This Setup Works

The Golden Piggy excels at generating steady, high-value XP ticks, especially when fed properly. When you combine it with six Ruby Squids—each boosting XP output and triggering frequent activations—you get a smooth, reliable XP engine that rarely misses a beat.

Using a mix of gold bars, medium treats, and small treats, players can hit around 735 XP per second, which is extremely strong considering how easy it is to run this combo at normal weight.

High-weight pets scale even better; a heavier Golden Piggy or heavy Ruby Squids can essentially cover the entire garden, improving hit consistency and XP uptime.

Challenges & Resource Requirements

The only real bottleneck is crafting 175 Gold Ingots, which can be time-consuming if you're early in progression. Fortunately, there are ways to speed this up:

Pacisphilosaurus helps reduce gold-related crafting requirements.

Orangutan pets provide crafting bonuses and can accelerate gold production dramatically.

With this support, even mid-game players can comfortably access the Golden Piggy route.

Conclusion

At 16 minutes from level 0 to 30, this combo is fast, reliable, and ideal for players with some crafting infrastructure. It remains one of the most popular setups in the entire community for good reason.

Combo 2: Mimic Octopus + Dilophosaurus

Time from Level 0 → 30: ~25 minutes

XP Per Second: High, but slightly below Golden Piggy

Difficulty: Easy (requires toys but no rare items)

Next we have the classic and extremely accessible Mimic Octopus + Dilophosaurus combo. This has long been a community favorite thanks to its simplicity, low resource cost, and surprisingly scalable potential.

Why This Combo Is So Beginner-Friendly

Many players recently followed guides to farm large quantities of toys overnight, meaning toys are no longer a limiting factor. With this newfound toy surplus, you can transform ordinary Mimic Octopuses into 15-second Giant Mimic Octopuses at will.

These giant versions drastically increase activation consistency, allowing players to create something close to an XP loop when paired with a Dilophosaurus.

The Concept of the “Infinite Loop”

By preparing several Mimic Octopuses in advance:

Each Mimic copies the skill of Dilophosaurus.

The reset timer is reduced to 15 seconds.

XP delivery becomes much more frequent.

Momentum builds and compounds as multiple activations overlap.

Although this still doesn’t reach the insane efficiency of the top-tier setups, the stability it provides is invaluable.

Testing Results

With optimized cycling, the combo reached level 30 in roughly 25 minutes—slower than Golden Piggy, but requiring significantly fewer special resources.

Conclusion

If you don’t have rare pets, don’t want to craft hundreds of ingots, or simply prefer a low-maintenance setup, the Mimic + Dilo combo remains one of the best options in the game.

Combo 3: Mimic Octopus + Frost Dragon (Battle Pass Pet)

Time from Level 0 → 18: ~1 minute

Time from Level 0 → 30: Varies (can be very slow)

Difficulty: High (Battle Pass pet + manual maintenance)

Now things get interesting.

The Frost Dragon, the newest Battle Pass pet, is a powerful yet unpredictable XP engine. It offers some of the highest burst XP in the game, but with enough drawbacks to prevent it from dominating the top of the leaderboard.

Why Frost Dragon Seems Broken at First

The Frost Dragon’s ability allows each pet to gain up to 10,000 XP per activation, which is an extraordinary number. Now combine that with a 15-second Mimic Octopus, and suddenly you’re hitting 10,000 XP every 15 seconds—meaning you exceed the output of even a Rainbow Dilophosaurus.

In our testing, the results were incredible:

Level 0 → 18 in just one minute

Smooth activation chains

Insanely high XP bursts while mutation conditions are met

But Then the Downside Hits

The Frost Dragon ability relies on frozen mutations, and once these are converted into glacial mutations, the skill simply stops working. At that point, you must:

Harvest all mutation fruits

Reset and reapply all mutations

Restart the activation process

This interrupts XP uptime and leads to long downtimes.

Conclusion

The burst is unmatched, but the maintenance kills the speedrun viability. While great for mid-level grinding or mutation farming, it’s not efficient for a clean 0-30 power leveling run.

Combo 4: Mimic Octopus + Rainbow Dilophosaurus

Time from Level 0 → 30: ~2 minutes

XP Per Second: Essentially infinite

Difficulty: Extremely high (rare pet + expensive)

Here it is—the undisputed king of XP combos.

The pairing of a Mimic Octopus with a Rainbow Dilophosaurus is the fastest leveling combo in the entire game, capable of taking a pet from level 0 to 30 in just two minutes.

Why This Combo Is So OP

Rainbow Dilophosaurus has always been one of the strongest pets in Grow a Garden, but when its skill is copied by a 15-second Mimic Octopus, the XP gain becomes nearly unlimited due to:

Massive scaling

High multiplier stacking

Incredibly short activation cooldowns

Perfect uptime across the whole garden

Even without a heavy one, you can still maximize efficiency by feeding it high-quality toys buy Grow a Garden Items.

The Real Challenge: Obtaining a Rainbow Dilophosaurus

This is where reality hits.

In Trade World, its price is 20,000+ tokens

Even when you have the tokens, the pet is often not available

The drop chance for Rainbow Dilo remains extremely low

And if you do manage to obtain one, there’s one more optimization step:

Using an Elephant to Max-Weight the Dilophosaurus

You can use Elephant synergy to increase your Rainbow Dilophosaurus up to its maximum 61 kg giant form, which expands its range and maximizes every possible activation.
