How to Trade in Pet Simulator 99 🛒✨

Trading in Pet Simulator 99 feels effortless, and the best part is—you don’t need to overwork to unlock trading features. You don’t even need to climb new levels or carry out hidden quests. From the very moment you step into the game, you’re free to connect and trade with other players.

Here’s exactly how to do it:

Open your pet menu by clicking the little icon at the bottom of your screen.
Next, spot the trade icon—it looks like two arrows pointing in opposite directions (super easy to recognize).
With one click, the trading interface slides open.
The game will instantly show you a list of every player in your server who’s open to trades.
Simply, tap the name of the player you choose, and boom—a trade request is on its way.

If they accept, a shiny new trade window pops up. It’s divided into two neat sections: my offers on one side and theirs on the other.

And this is where the magic happens—your pets, items, or diamonds will go in one particular slot, while you watch what the other player puts up for grabs. Every trade is a little negotiation dance, and it’s always important to double-check before locking it in.

Where is the TRADING PLAZA in Pet Simulator 99? 🌍

Finding the Trading Plaza in Pet Simulator 99 isn’t complicated at all—follow these simple steps:

👉 When you first spawn into the game near the Pet Shop, don’t wander around. Head straight toward the farming areas.

👉 As you make your way to Area 3, pay attention to your left-hand side—you’ll see a massive castle towering over the map. That castle is the entrance to the Trading Plaza.

👉 Step inside the castle, and you’ll notice two shimmering portals waiting for you. These portals decide the type of trading world you’ll enter:

One leads to the Normal Trading Plaza, where most players start.
The other leads to the Pro Trading Plaza, designed for high-value traders.

👉 Both portals open up exclusive trading servers—your job is to pick the one that matches your progress and your trading goals.

⚠️ But here’s the catch: the Pro Trading Plaza isn’t for everyone. To walk through that door, you’ll need 5 Huge Pets or 1 Titanic Pet in your inventory. Some players even buy Robux to hatch Huge pets faster, just so they can unlock Pro access earlier than everyone else.

How to Access the Trading Plaza 🔑

Before you can even step foot inside the castle, you’ll need the all-important Castle Key. Without it, the plaza stays locked.

👉 So how do you get this Castle Key? You’ll need to complete your very first Rebirth.

👉 To trigger a rebirth, push forward in the game until you reach Area 25. When you arrive, look for a giant Golden Cat Statue standing proudly in the zone. Interact with it, and the rebirth process begins.

👉 Once you rebirth, the game resets you back to the beginning. Yes, you’ll lose access to your unlocked areas—but don’t panic. This reset comes with incredible rewards.

Here’s what you gain from your first rebirth:

✅ The Castle Key (which unlocks the Trading Plaza).
✅ A permanent pet power boost to make your pets stronger forever.
✅ 10,000 Diamonds to kickstart your second journey.
✅ The ability to teleport, letting you zoom across areas without wasting time.

👉 Your second run through the game will be smoother and much faster than your first. You’ll rebuild progress in no time.

👉 Once you’ve completed that first rebirth and claimed your Castle Key, head back to the castle. Step inside, choose your portal, and join the world of Pet Sim 99 Trading—whether it’s casual deals in the normal server or high-stakes trades in the Pro Plaza.

How To Unlock TRADING PLAZA in Pet Simulator X

Many players confuse PS99 with Pet Simulator X. While they are different titles, the unlocking system is nearly identical. In both, you’ll need a special key and progression milestones to access the plaza.

This creates a sense of accomplishment, ensuring only dedicated players reach the elite trading hub.
