Pet Simulator 99 Chrome Egg is the new limited-time Exclusive Egg introduced with Update 100 on 31 October 2026. It contains seven named Chrome pets, including Gargantuan Chrome Unicorn, Titanic Chrome Panda and two Huge pets, and is available through the Exclusive Shop and the Forever Pack reward trail.
This is a paid-shop egg, not one of the five new Haunted Farm zone eggs. BIG Games also sells a separate Wicked Pack during the Halloween update, but its published contents do not identify the three included Exclusive Eggs as Chrome Eggs. Check the actual offer rather than assume every pack contains the new release.
Every pet inside the Pet Simulator 99 Chrome Egg
The Pet Simulator 99 Chrome Egg pool has seven publisher-confirmed pets. Its rarest named prize is Gargantuan Chrome Unicorn, followed by Titanic Chrome Panda. There are two Huge pets, Huge Chrome Axolotl and Huge Chrome Monkey, plus the standard Exclusive Chrome Axolotl, Chrome Dog and Chrome Monkey.
| Pet | Rarity |
|---|---|
| Gargantuan Chrome Unicorn | Gargantuan |
| Titanic Chrome Panda | Titanic |
| Huge Chrome Axolotl | Huge |
| Huge Chrome Monkey | Huge |
| Chrome Axolotl | Exclusive pet |
| Chrome Dog | Exclusive pet |
| Chrome Monkey | Exclusive pet |
The Huge Chrome Axolotl and ordinary Chrome Axolotl are different items, as are Huge Chrome Monkey and the regular Chrome Monkey. A Chrome Dog is also part of the Exclusive pet pool, but the publisher does not name a Huge Chrome Dog in the egg. Read the full name when checking what you have hatched.
Where to find the Pet Simulator 99 Chrome Egg
BIG Games confirms the Pet Simulator 99 Chrome Egg in the in-game Exclusive Shop. It can also appear on the Forever Pack trail, where players progress through a sequence of offers and rewards. Those are its two confirmed shop locations. BIG Games calls the egg limited-time but does not specify when it leaves the shop.
Open the current Exclusive Shop or Forever Pack page in Pet Simulator 99 and check the item description and displayed price before purchasing. The official announcement names the pet pool and both shop locations but does not print a fixed Robux price or every step in the Forever Pack trail.
The Exclusive Chrome Egg is separate from the Haunted Farm eggs purchased with Candy Coins. Five farm zones have their own eggs, purchased with event Candy Coins, and the final zone egg can hatch Huge Guard Rhino. You do not need the Chrome Egg to enter the Halloween Games, earn Spirit Shards or try the Forge.
Chrome Egg compared with the Forever Pack
The Forever Pack features the Pet Simulator 99 Chrome Egg as part of its reward trail, but it has other pets too. The named headline prizes include Gargantuan Porcelain Doll Cat, Titanic Bedsheet Giraffe and Huge Butler Penguin. Those are Forever Pack features and should not be added to the seven-pet Chrome Egg hatch list.
The Forever Pack also offers Tier II Tricks for use in Halloween Games. Tricks include useful survival effects such as a Flashlight that reveals a hidden hint, a Broomstick that skips the next game, a Lucky Charm that blocks a knockout and a Treat Magnet that boosts Treats for one game. These are gameplay items, not additional Chrome pets.
Does the Wicked Pack contain Chrome Eggs?
BIG Games lists three Exclusive Eggs in the Wicked Pack, along with Tier II Tricks, 50 Midnight Gifts, one million Candy Coins and a Mega Ultimate Chest. That official list does not name the Pet Simulator 99 Chrome Egg as any of the three eggs. Treat the pack as a different bundle unless its live purchase screen explicitly shows the Chrome Egg.
Midnight Gifts are also earned through Halloween Games and can contain Treats, Candy Coins, Tricks and Huge Neon Skeleton Dino. Candy Coins are used on the Haunted Farm. Buying a Wicked Pack therefore brings several different event resources, but it does not automatically prove that its Exclusive Eggs match the Chrome pool.
Are Pet Simulator 99 Chrome Egg Gargantuan and Titanic odds guaranteed?
No guaranteed Gargantuan or Titanic roll is stated in the Pet Simulator 99 Chrome Egg announcement. The seven-pet list tells you what’s inside, but it isn’t a statement of equal hatch chances. Limited-time availability doesn’t guarantee a high-rarity hatch. Check the current in-game hatch information rather than infer a rate from the order in which BIG Games shows its pet pictures.
The same caution applies to the Halloween Forge. It has its own Titanic Neon Skeleton Cat, with 3,000 copies released globally, and a chance at Gargantuan Butler Penguin. Those pets do not appear in the Chrome Egg pool. The Chrome Unicorn and Chrome Panda are the higher-rarity targets for this particular egg.
Free Halloween pet routes versus shop pets
If you do not want to spend Robux, the Pet Simulator 99 Chrome Egg is not required for the major free-play activities in Update 100. Play Halloween Games to earn Spirit Shards for Forge luck, Treats for the individual leaderboard and Midnight Gifts. Event quests supply Season Tokens to reach the free Tier 4 Huge Guard Bat.
There are also three Huge rewards associated with the Forge stages, Huge Guard Rhino in the final farm egg, Huge Witch Cat from the Cursed Egg in PSX Classic and clan or individual leaderboard Huge prizes. These rewards have their own gameplay conditions. They are not an alternate way to open a Chrome Egg or guaranteed substitutes for its pet designs.
What to check before buying the Pet Simulator 99 Chrome Egg
Before buying, check the contents and displayed cost of the specific egg or pack. Keep the Chrome Egg separate from the Wicked and Forever Pack offers. Decide whether you want the Chrome pet pool itself or one of the different seasonal bundles. The shop range includes several similarly named Huges, Titanics and Gargantuans, and the exact source matters.
BIG Games calls the Pet Simulator 99 Chrome Egg limited-time, so the offer will not stay on sale indefinitely. It has not named an exact departure hour in the published Update 100 notes. Keep purchases within Pet Simulator 99 and never give another player a Roblox password or Security PIN in exchange for a claimed discounted egg.
