Pet Simulator 99 has been on a roll lately, and if you have been keeping up with the weekly Saturday drops from BIG Games, you already know the pace of content has been relentless. Between the Spring Event receiving a major overhaul and Fantasy World continuing to expand with Time Trials and the Combine-o-Matic, there is a lot to unpack. We are going to walk you through everything added across these updates, and more importantly, what you should actually be doing right now to stay ahead.
Spring Event Gets a Big Second Wind
The Spring Event received a significant refresh that brought in content many players were not expecting. The biggest new addition is The Nest, a fifth zone that opens once you unlock Egg 5. Inside The Nest sits the brand new Boss Chest, and this one is not like your regular breakables. Smashing it down rewards coins, the Huge Lamb Wolf, and the Titanic Butterfly Pony, while also earning you Spring Boss Chest Tokens that you can spend on two brand new upgrade tracks: Huge Hunter and Titanic Hunter. These upgrades directly boost your chances of pulling rare pets from the Boss Chest, so prioritizing your tokens here is a smart call if you are chasing anything above a regular Huge.
Also added to The Nest is a brand new raffle. Break more Boss Chests and you stack more chances to win the Huge Spring Kitten, which can also drop as Golden, Rainbow, or Shiny. From personal experience watching players attempt this, the raffle ticket flow inside The Nest is slower than the other zones since the Boss Chest is the only breakable, so do not expect raffle tickets to pile up quickly here.
The egg lineup itself was also refreshed. New eggs now offer progressively better pets, with the final egg housing the Gargantuan Bloom Dominus, making this one of the more stacked spring events in the game’s history.
The Retirement Merchant: A Quiet but Important Addition
One of the updates many players glossed over is the Retirement Merchant, and I think that is a mistake. A new Retirement Merchant has appeared in the Trading Plaza where you can sell old Huge pets for diamonds. The list of accepted pets is chosen by the admins and rotates, so checking back frequently is worth your time. Stock is limited per pet, and you earn bonus diamonds for selling Golden, Rainbow, or Shiny variants.
This is actually a meaningful quality-of-life addition. For players sitting on older Huges that have dropped in trade value, this creates a reliable exit route that does not depend on finding a willing buyer in the plaza. It will not make you rich, but it reduces the dead weight in your inventory and gives you something functional in return.
Huge and Spinny Wheel Refreshes Across the Game
Beyond the Spring Event, the update also delivered a full world refresh on Huge pets across every major chest and Spinny Wheel in the game. Here is a quick breakdown of what changed:
- Huge Vibrant Whale is now in the Crystal Chest
- Huge Inkwell Wisp moved into the Fantasy Chest
- Huge Robot replaced the old pet in the Tech Chest
- Huge Quantum Griffin now sits in the Void Chest
- Huge Prison Cow is the new resident of the Prison Chest
The Spinny Wheels were also refreshed across the board. The starter Spinny Wheel now features the Huge Carnival Panda, the Fantasy Wheel carries the Huge Sprout Wormling, the Tech Wheel offers the Huge Fragmented Pterodactyl, and the Void Wheel now spins for the Huge Wireframe Cat. Additionally, the Millionaire World’s raffle was updated, and the Elemental World’s final egg pool was also changed. These refreshes are genuinely useful for players who might not have many Huges yet, since grinding the older chests and wheels now gives you something worth pursuing again.
Fantasy World: Time Trials, Combine-o-Matic, and New Pets
Fantasy World remains one of the most ambitious additions BIG Games has made to Pet Simulator 99 in a long time. It is only the fourth world ever added to the game in its history, which gives you a sense of how significant this release was. The world launched with 10 zones and has been expanding with each update since.
The highlight feature for competitive players is the Time Trials. Located in the Fantasy World, Time Trials is a minigame where players compete to destroy all the breakables in each pile as quickly as possible. There are 5 tiles, each with 6 waves of breakables, followed by a final boss wave. The faster you destroy the breakables, the more points you earn, and those points can be used to unlock chests containing the Titanic Starlight Pony, Huge Starry Eye Bunny, or the Huge Telescope Owl.
The updated version of Time Trials is now about consistency rather than just raw speed. You earn points based on speed, improvement, and daily streak, can play up to 10 times a day, and are rewarded for simply showing up regularly. This is a meaningful change from earlier iterations that rewarded only the absolute fastest players. If you have been putting off engaging with Time Trials because it felt out of reach, now is the time to get back into it.
The Combine-o-Matic has also received new pets exclusive to Fantasy World. You can combine your shards for the Huge Angel Dragon, which is available for a limited time inside the world. We have always thought the Combine-o-Matic is underrated by casual players, and with new pets in the pool, it is worth revisiting your shard stockpile before they become tradeable items in the plaza at inflated prices.
What You Should Be Stockpiling Right Now
Given how Time Trials rewards work and how new zones keep arriving in Fantasy World, there are a few items worth grabbing now before prices rise in the trading plaza.
- Cocktail 2 potions remain one of the most efficient boosts for hatching eggs and Time Trial prep, but they can go for 15 to 70 million gems depending on who is selling, so buying early is smarter than waiting.
- Luck potions directly improve your odds on stat pets, which matters once a new best pet for the current Time Trials zone is established.
- Enchants from the Spring Event, particularly chest breakers and orb enchants, are worth holding onto. They tend to jump in price once a new Time Trials zone opens and players start optimizing their setups.
- New quality-of-life features like inventory sorting by power, name, or RAP, egg potato mode for near-instant hatches, and server profiles now working anywhere in the game all make building your setup more manageable than it used to be.
One item people are sleeping on is the shiny hoverboard. It is expensive, with a floor price sitting around 1.5 billion gems, but it saves roughly 10 seconds in Time Trials runs compared to a regular hoverboard. Over many attempts, that adds up.
Final Thoughts
Pet Simulator 99 is in a strong content cycle right now. The Spring Event Part 2 addressed complaints about the first part by adding actual stakes with the Boss Chest and a new Gargantuan-tier pet. Fantasy World keeps growing, and Time Trials has been redesigned to reward dedication over raw speed. If you are on the fence about engaging with either, we would say the Time Trials rework alone is worth logging back in for.
