Roblox: The Most Valuable Pets In Pet Simulator 99

Roblox - Game

WHERE TO PLAY

Roblox is enjoyed by millions. A sandbox game where you can play, create, and come together with people all over the world. Jump into any of the community experiences, or take advantage of promo codes for cool content. 

Building up your collection and trading with other players is a core part of Pet Simulator 99, one of the biggest experiences on the Roblox platform. As with any collectible, there are some pets that are rare and valuable enough to command a hefty price in in-game Diamonds, or an equivalent trade.

Pet Simulator X: How To Transfer Pets To Pet Simulator 99

Pet Simulator 99 is coming on December 1! Get ready by sending your best pets over from Pet Simulator X.

While it's not uncommon for pets to cross the million-Diamond threshold in terms of price, several can reach several hundred times that amount! We've put together a list of the most valuable pets in PS99 and how much they're currently worth.

We use Cosmic Values, one of the most trusted fan resources, to determine the price of each pet. All values are listed in in-game Diamonds, and are subject to change. Remember to observe basic Internet safety and follow the Roblox Terms of Service when trading. We last updated this list based on the current value listings on January 24, 2024.

10 Titanic Balloon Monkey

750 Million Diamonds

Like the Titanic Mystic Corgi, the Titanic Balloon Monkey was a Pet Simulator X exclusive, so there won't be any new ones added to Pet Simulator 99.

9 Titanic Mystic Corgi

770 Million Diamonds

Plenty of pets that were available through Exclusive Eggs in Pet Simulator X are no longer available in Pet Simulator 99. For that reason, you can expect the value of pets like the Titanic Mystic Corgi to grow steadily over time, since no more will be hatched.
