Pet Simulator 99 Classic Index lets you track every pet you discover in PSX Classic while earning points for your clan in the Fantasy Clan Battle. The Index arrived alongside the Update 99 portal on October 24, 2026, and gives collectors another reason to explore the old Pet Simulator X world.
Each new Classic pet contributes towards the clan competition, while Classic Huge pets have their own dedicated row. Here’s how discoveries count, which rare pets you can chase and how to combine Index progress with area and Season Pass rewards.
The PSX Classic Portal guide explains how to enter, and our Update 99 overview covers the full event.
Where to find the Pet Simulator 99 Classic Index
The Classic Index belongs to the PSX Classic event added on October 24, 2026. First enter the PSX portal behind the eggs in the main PS99 area, or use Join Event on the sidebar. Once inside, explore the Classic world and open the Index interface to check which pets you have obtained. The Pet Simulator 99 Classic Index is specifically for pets you collect in this event, so it is useful even if you already own a sizeable pet collection in the normal game.
How to add pets to the Pet Simulator 99 Classic Index
Start by hatching eggs as you move through Town, Spawn and the Fantasy areas. The Classic Index records the different pets you obtain in PSX Classic. A new pet is a useful discovery for both your collection and your clan’s score. As a result, hatching a variety of eggs is valuable even when the resulting pet is not stronger than your current team. The Pet Simulator 99 Classic Index is about collecting different entries, not simply getting the most copies of one pet.
Pet Simulator 99 Classic Index: Classic Huge pets
BIG Games says Classic Huge pets occupy a separate row of the Index. There are multiple ways to find them: Huge Dalmatian can hatch from any Classic egg; Huge Tiger comes from the final Empyrean Egg; and Huge Agony is associated with the Grand Heaven Chest near the end of the route. These are chance-based rewards, so none is guaranteed by reaching a particular area. Pet Simulator 99 Classic Index completion will take longer if you are chasing these rarer entries as well as ordinary egg pets.
Pet Simulator 99 Classic Index and clan points
Every new pet discovered in the Pet Simulator 99 Classic Index contributes points to your clan during the Fantasy Clan Battle. The developer also lists completing achievements and hatching Huges as scoring activities. It has not released a complete table of point values per individual pet in its public announcement, so avoid treating every discovery as if it awards an identical fixed number. What is clear is that finding uncollected pets contributes, meaning a broad collection can be more useful than repeatedly hatching only one familiar egg.
Best way to fill your Pet Simulator 99 Classic Index
Begin in early Town areas and hatch enough eggs to obtain the available varieties, then open new sections and repeat. If coins are limited, advance with stronger pets before returning for missing entries. Check the Index after each stretch of hatching so you can see what remains, then focus on eggs that offer something you have yet to collect. The Pet Simulator 99 Classic Index rewards exploring the whole event rather than staying in the opening area indefinitely. Late-game players can spend more time at the Empyrean Egg and Grand Heaven Chest while pursuing rare Huge drops.
Pet Simulator 99 Classic Index: Do Twins count twice?
When you hatch a Classic Huge, the original remains in the Classic world and a Classic Twin is added to your PS99 account when you return home. Trading inside Classic is disabled. BIG Games does not state that receiving the twin creates an additional Classic Index discovery or doubles clan points, so count on the original pet discovery rather than treating its PS99 twin as a bonus scoring entry. The Pet Simulator 99 Classic Index and your regular PS99 inventory are connected by this reward system but serve different purposes.
Pet Simulator 99 Classic Index: Fantasy Clan Battle rewards
The six-day Fantasy Clan Battle rewards the whole clan based on final placement. First place receives Gargantuan Meebo in a Spaceship. Second and third earn Rainbow Titanic Empyrean Dragon, places four to ten earn the Golden version, and places eleven to fifty earn Titanic Empyrean Dragon. Places fifty-one to two hundred and fifty receive Huge Empyrean Fox. There are also Portal Hoverboard, Portal Booth, Clan Gift and medal rewards tied to rankings. Your Pet Simulator 99 Classic Index progress is one of several ways to help the team climb these brackets.
Clan points versus the individual leaderboard
The Fantasy Clan Battle is not the same as the PSX Classic individual leaderboard. The individual event scores rarer pet hatches more heavily, with prizes including Gargantuan Angelus, Titanic Glitched Phoenix and Huge Reaper at different ranks. The clan event separately counts achievements, Index discoveries and Huge hatches. Before prioritising your next activity, check whether you are pursuing personal placement, clan placement or simply completing the Pet Simulator 99 Classic Index for your own collection.
Pet Simulator 99 Classic Index: Other rewards
You can earn Season Pass tokens by hatching eggs, breaking chests and reaching new areas, with a free Huge Froggy awarded at Tier 4. All eighteen PSX Classic areas also grant PS99 rewards when you use Home to return, and your first return includes 100,000 Diamonds and 10 Mini Chests. This means time spent expanding your Pet Simulator 99 Classic Index can also move several other objectives forward. Alternate new egg discoveries with advancing areas, then collect your main-game rewards before returning for more.
For another long-term Classic objective, see Classic Legend. The existing Diamond Mountain, Secret Trails, Expeditions and Yeti leaderboard have separate prizes.
