Pet Simulator 99 Update 101 arrived on 7 November 2026 with the Masquerade Games, the Combine-o-Matic and new rewards. If you played the previous Halloween Games, there is an important change: Masquerade matches now have 20 players instead of 40, and the two new competitions track Treats differently.
Even if you aren’t chasing a ranking, there’s plenty to do. You can explore three new zones, hatch Huge Bat Hoodie Panda, collect stronger Tricks or combine pets all the way up to Gargantuan Butler Penguin. Start with the reward you actually want.
What’s new in Pet Simulator 99 Update 101?
To enter the Masquerade Games, walk through the haunted door. BIG Games names Broom Sweep, Bumper Pumpkins Final, Lights Out and Gloomkin among the new minigames. You will jump over the witch’s broom, bump rivals in pumpkin cars, freeze at the right moment and hide from Gloomkin. Not every round has a published step-by-step explanation, so learn the rules as you play instead of trusting unverified collision timings.
Surviving games earns Treats, Midnight Gifts and Spirit Shards. Treats buy upgrades, while Midnight Gifts can contain Tricks. The longer you stay in the competition, the more useful each match becomes. Remember that the new solo leaderboard counts only Treats earned in matches, not the Treats you collect while farming outside them.
Pet Simulator 99 Update 101 zones and eggs
Pet Simulator 99 Update 101 brings Witch Village, Masquerade Ball and Thorn Spire. They have the Witch Hat Egg, Ballroom Egg and Thorn Egg respectively. Work through the zones in that order to reach the last egg, which can hatch the Huge Bat Hoodie Panda. That Huge is an egg reward, not the leaderboard’s Huge Jester Lion.
| Zone | Egg | Key reward |
|---|---|---|
| Witch Village | Witch Hat Egg | Opens access to Treat Finder |
| Masquerade Ball | Ballroom Egg | Second new event egg |
| Thorn Spire | Thorn Egg | Chance to hatch Huge Bat Hoodie Panda |
Pet Simulator 99 Update 101 Combine-o-Matic pets
The Combine-o-Matic starts with Huge Bat Hoodie Bunny, then Huge Witch Fox and Huge Thorn Dragon. From there, its headline prizes are Titanic Masquerade Agony and Gargantuan Butler Penguin. Combines can also produce Golden, Rainbow and Shiny versions, but the publisher has not given the odds for those outcomes.
Before you combine anything, inspect the machine in the game. The official notes list the progression but not the exact number of pets required at every step. Forge Saver reduces the number of pets needed, so it is worth checking if you are preparing a longer combining session. Do not confuse the new Combine-o-Matic with the old Halloween Forge.

Treat upgrades in Pet Simulator 99 Update 101
Three Treat-funded upgrades have been added. Forge Saver makes combining cheaper by using fewer pets. Trick Finder improves Trick drops from breakables. Treat Finder increases the Treats earned in matches and becomes available once you enter Witch Village. Choose based on what you plan to do next; there is little point buying a combining upgrade if you only intend to play survival matches.
Check the current machine for upgrade costs. Breakables and Midnight Gifts are the confirmed ways to collect Tricks through normal gameplay.
Tier III Tricks and survival
The four new Tier III Tricks are stronger versions of the familiar items. Flashlight reveals a hidden hint for nine seconds. Broomstick safely skips three games. Lucky Charm blocks three knockouts. Treat Magnet gives four times as many Treats for one game. That last effect is clearly a Treat multiplier, but the developer has not separately confirmed how it affects competitive score calculation.
Players struggling to stay in the match might prefer Broomstick or Lucky Charm, while Treat Magnet suits someone farming event currency. The Tier 3 Tricks guide goes through all four effects and the best sources.

Pet Simulator 99 Update 101 leaderboard and League
There are two different competitions. In the solo Masquerade Leaderboard, only Treats won inside games count towards your position. Places 1 to 3 get Gargantuan Butler Penguin, with Titanic Phantom Tiger variants in subsequent prize tiers and Huge Jester Lion awarded through rank 10,000.
The four-person Masquerade League is different: it counts Treats earned in games and from farming. Its top team gets Gargantuan Butler Penguin, and prizes extend to the top 5,000 teams. Check our solo rankings and reward table and four-player League guide before you choose where to spend your time.
When does Pet Simulator 99 Update 101 end?
Solo leaderboard scoring ends on Friday, 13 November 2026. BIG Games also lists the current Masquerade League as running from 7 to 13 November. No universal exact finish hour is given in the main update notes, so check the in-game countdown rather than assuming a particular UK time.
The Masquerade pets remain trade-locked until Saturday, 14 November. That restriction is separate from the scoring deadline. Week four of the Season Pass also remains open, including the free Huge Guard Bat if you are still collecting the required Season Tokens.
A good first route through Pet Simulator 99 Update 101 is a few matches for Treats and Midnight Gifts, followed by Witch Village and the upgrade you need. Head to Thorn Spire for the Huge egg, or focus on matches and team farming if you want a leaderboard reward.
