How to Get the Easiest Huge Pet in Pet Simulator 99 Slime Factory Guide
Getting a Huge Pet in Pet Simulator 99 usually takes a lot of grinding, time, or even luck — but not this time. With the new Slime Factory update, players now have a much easier way to get a Huge Pet compared to past methods. In this guide, we’ll break down exactly how you can get your hands on the Huge Ooze Axolotl, one of the simplest Huge Pets to obtain right now. Let’s go step by step on what you need to do and how to improve your odds of hatching or earning this pet through passive farming.
Why the Huge Ooze Axolotl is the Easiest Huge Pet?

The Slime Factory update added several new Huge Pets, but not all are created equal when it comes to accessibility. Among them, the Huge Ooze Axolotl stands out because:
-
It can drop from regular breakables inside the Slime Factory.
-
You don’t need to hatch eggs or rely on complicated mechanics.
-
It works with AFK farming, making it nearly passive.
-
No Game Pass required — although having the Auto-Farm Game Pass helps a lot.
With over 113,000 Huge Ooze Axolotls already hatched, it’s clear that this pet is one of the easiest and most reliable Huge Pets to grind for.
Step-by-Step Guide to Getting the Huge Ooze Axolotl

Here’s how you can start farming it today:
1. Farm Breakables Inside the Slime Factory
Just break anything you see in the area — from small objects to green chests. According to several players, larger breakables (like green chests) may have a higher drop rate for the Huge Ooze Axolotl.
2. Upgrade “Better Breakable Huge Luck”
In the Upgrade Machine, focus on maxing out the third upgrade from the top, which boosts your odds of getting a Huge Pet from breakables. Once maxed, this upgrade gives you a 300x chance compared to the default, which is a major boost.
3. AFK Farming Tips
-
Place your pets on breakables and just let them grind while you’re AFK.
-
You don’t have to be active all the time — just check in once in a while.
-
If you don’t have the Auto-Farm pass, you can still participate, but you’ll need to manually place pets on breakables more often.
4. Use Factory Boosts for Coins and Damage
Boosts like Coin and Damage Boosters make farming quicker. More damage means faster breakables, which in turn gives you more chances to trigger the Huge drop.
5. Hatch While You Farm
If you’re still sitting in the area, you might as well open up some eggs. Use non-charged eggs to save gems (1M per egg compared to 20M with charged eggs), and you’ll get more value for the same cost.
With more than 100,000 Huge Ooze Axolotls already in circulation, the answer is yes. As long as you keep grinding and upgrading, your odds are solid. Compared to the Huge Night Slime or Titanic Jolly Cat, which are much rarer, this Huge Pet is a realistic goal even for casual players.
The Huge Ooze Axolotl is easily the most accessible Huge Pet in Pet Simulator 99 right now. With a bit of preparation and smart upgrades, you can literally AFK your way into scoring one. If you haven’t started grinding the Slime Factory yet, now’s the time. And don’t forget — upgrades matter. Max out your chances, let your pets do the work, and you might just log back in to find a Huge waiting for you.
