Quick answer: As of October 23, 2026, we could not verify a public official announcement or reliable primary-source evidence confirming that new Pet Simulator 99 pet models have leaked from Update 99 test servers. The latest official update we could confirm is Update 98, “Diamond Mountain,” published by BIG Games on October 17. Treat screenshots or model lists circulating without a traceable source as unverified—not confirmed leaks.
Pet Simulator 99 players are watching for the next update, and alleged test-server images can spread quickly. But a convincing render is not proof that a model is real, scheduled for release, or available in the live game. This guide separates what is confirmed from what players should check before sharing or trading based on a rumor.
What is confirmed about Pet Simulator 99 right now?
BIG Games’ official Update 98 post is titled “Diamond Mountain!” and is dated October 17, 2026. It describes six mountain camps, Rubble Walls that award Diamonds, the Abominable Yeti encounter, summit trails, expeditions, a Season Pass, and new pets. The official notes identify rewards including the Huge Expedition Wolf, Huge Hiker Raccoon, Titanic Expedition Leopard, and Gargantuan Abominable Yeti.
That official update is the reliable baseline for comparing claims about new models. The notes do not establish that an Update 99 pet roster has leaked. We found no official confirmation in the material reviewed that validates the headline claim of new models from test servers.
How to check whether an alleged Update 99 pet leak is real
- Find the original source. Prefer a direct post from BIG Games or an identifiable developer or creator. Reposted screenshots without provenance are weak evidence.
- Look for an official update post. Check the BIG Games developer blog and the official Pet Simulator 99 Roblox page.
- Check the context, not just the image. Old update art, edited renders, fan concepts, and test assets can be mistaken for upcoming content.
- Do not assume a model is obtainable. Even a genuine development asset does not prove a release date, hatch odds, trading status, or final name.
- Wait before trading for a rumor. Do not pay extra for a pet based only on an unverified screenshot or a claimed future value.
Which new pets were actually named in the latest confirmed update?
The official Diamond Mountain notes list several new rewards and pets, including the Huge Climber Bear, Huge Climber Goat, Huge Hiker Red Panda, Huge Hiker Raccoon, Huge Expedition Wolf, Titanic Amber Markhor, Titanic Equinox Deer, Titanic Expedition Leopard, and Gargantuan Abominable Yeti. The same post also describes pets associated with the Exclusive Remix Egg and Forever Pack. These are confirmed Update 98 details; they should not be relabeled as leaked Update 99 pets.
Will Update 99 add new pet models?
It may, but that is not enough to report a leak as fact. Until BIG Games publishes Update 99 notes or a verifiable primary-source preview appears, the exact models, names, rarity tiers, hatch methods, and release timing remain unconfirmed. We will update this report if a reliable source establishes those details.
