If you've spent any time looking for a shortcut to get more gems or Huge pets, you've probably stumbled across a roblox pet simulator 99 mail stealer script being promoted in a Discord server or a YouTube description. It's one of those things that looks like a dream come true—a script that promises to "dupe" items or "autofarm" billions of gems while you sleep. But the reality is a lot messier, and honestly, pretty devastating for anyone who actually tries to run one.
The Pet Simulator 99 community is huge, and because the economy revolves around high-value items that take months to earn, players are always looking for a way to get ahead. Scammers know this. They create these scripts not to help you, but to clean out your inventory the second you hit "execute."
How these scripts actually work
Most people think a script is just a bit of code that makes the game do something cool. While that can be true for legit exploits (which are still against the rules, by the way), a roblox pet simulator 99 mail stealer script is designed with one goal: theft.
When you copy and paste that "God Tier Luck" script into your executor, the code doesn't actually touch the game's RNG. Instead, it runs a background process that looks at your inventory and your gems. It then uses the in-game Mailbox system to send everything you own—your Huges, your Titanic pets, and your diamonds—to a username hardcoded into the script. The worst part? It does it so fast you might not even notice until you check your mail history and realize your inventory is empty.
These scripts often use something called "obfuscation." That's just a fancy way of saying the code is scrambled so you can't read it. If you open the script file and it looks like a bunch of random gibberish or long strings of letters and numbers, that's a massive red flag. They're hiding the part of the code that says "send all pets to Scammer123."
The bait that catches most players
Scammers are getting really good at marketing these things. They don't just post a link; they create entire YouTube channels dedicated to showing "proof" that the roblox pet simulator 99 mail stealer script works. You'll see videos of accounts with hundreds of Huges, supposedly gained through the script.
What you don't see is that those videos are often edited or filmed on private servers with "fake" pets. The comments under the video are usually filled with bots saying things like, "OMG this actually worked!" or "I just got 5 Titanic pets, thank you!" It's all a setup to make you feel like you're the only one missing out.
They also love to use titles like "NEW PATCHED BYPASS" or "AUTO DUPER 2024" to create a sense of urgency. They want you to think you have to use it right now before it gets fixed, so you don't take the time to think about whether it's safe.
Why the mailbox feature is targeted
In Pet Simulator 99, the mailbox is a convenient way to trade with friends or move items between your own accounts. It's also the perfect tool for a thief. Unlike a traditional trade where both players have to click "Accept" and wait for a countdown, the mailbox just sends the item instantly.
A roblox pet simulator 99 mail stealer script takes advantage of this by automating the mailing process. The script essentially "clicks" the buttons for you in the background. It selects your most valuable items first, enters the scammer's name, and hits send. It can do this for 50 items in the time it takes you to blink. By the time you realize the script didn't give you "Infinite Gems," your most valuable assets are already gone.
Red flags to look out for
If you're still tempted to try out scripts, you really need to know what a malicious one looks like. There are some dead giveaways that a roblox pet simulator 99 mail stealer script is trying to get into your pockets.
First, look for any mention of "loadstring" followed by a URL. This is a command that pulls code from an external website (like Pastebin or GitHub). While not always malicious, it's the easiest way for a scammer to hide what the script is actually doing. They can change the code on their end at any time, turning a "safe" script into a stealer instantly.
Second, be wary of scripts that require you to disable your anti-virus or ignore "False Positives" from your exploit executor. While some executors do get flagged as viruses because of how they interact with memory, a script itself should never be asking you to lower your security.
Lastly, if the script is being promoted as a "Dupe," it is 100% a scam. Item duplication doesn't exist in Pet Sim 99. The developers, BIG Games, have a pretty tight grip on the server-side logic. Anyone claiming they have a "dupe script" is just trying to get you to run their mail stealer.
What happens if you get hit?
It's a gut-wrenching feeling. You log in, or you're standing at the plaza, and suddenly your pet list starts shrinking. If you've run a roblox pet simulator 99 mail stealer script, the damage is usually permanent. Because the items were sent through the mailbox—a legitimate game feature—it's very hard to get them back.
Roblox support and BIG Games support generally won't restore items lost to scripts. Their stance is usually that you shouldn't have been using third-party software in the first place. This leaves the victim with a zeroed-out account and no real way to recover months of hard work.
Sometimes, these scripts do more than just steal your pets. Some of the more advanced ones can actually grab your "cookie," which is a piece of data that lets them log into your Roblox account without needing your password or 2FA. If that happens, they can change your password, spend your Robux, and lock you out entirely.
How to stay safe in the plaza
The best way to avoid a roblox pet simulator 99 mail stealer script is simple: don't use them. I know it's tempting when you see people walking around with Titanic pets that cost thousands of dollars, but there is no "easy button" in this game.
If you want to get rich in PS99, stick to the legitimate methods. Flip items in the Trading Plaza, use your enchants wisely, and participate in events. It takes longer, sure, but at least your account will still be there tomorrow.
Also, be careful about who you trust in Discord. Scammers often hang out in the big trading servers, DMing people who look like they have good items. They'll offer to "help you out" with a script or a "private trading tool." It's almost always a trap.
Final thoughts on the "free" script trap
At the end of the day, if something sounds too good to be true, it probably is. The people writing a roblox pet simulator 99 mail stealer script aren't doing it for fun or to "stick it to the devs." They're doing it to make real-world money by selling your stolen pets on "black market" sites.
It sucks that the community has to deal with this, but it's the reality of any game with a valuable economy. Protecting your account is your responsibility. Keep your 2FA turned on, never share your Roblox files, and for the love of everything, don't run random scripts you found on the internet. Your Huges will thank you.
