Pet Simulator 99 Update May 2026 — Void RNG Event & Titanic Pets
Pet Simulator 99 dropped Update 78 on May 9, 2026, introducing the Void RNG Event — a completely new RNG world with rolling mechanics, combo streaks, and some of the rarest pets the game has ever seen. The headliner is the Titanic Arcane Void Cat at a staggering 1 in 3 billion hatch rate, and there's a competitive Angel Clan Battle running alongside it. The event wraps up on May 23, so you've got about two weeks to grind it out.

What's New in the Void RNG Event
Update 78 adds an entirely separate area called the Void RNG World. It's built from the ground up around rolling mechanics — think of it as a dedicated luck-testing zone where every action feeds into your next roll.
You can access the RNG world from three locations: Spawn in the Starter World, Tech World, or Void World. Look for a blue-colored brick house with an "RNG Event" sign above the door. Walk through the void door inside and you'll start rolling for pets immediately.
Combo Streaks & Lucky Weather
The core loop revolves around consecutive rolls. Each successful roll builds your combo streak, and higher streaks grant increasingly large luck bonuses. This stacks fast — dedicated players are reporting 50x and 100x luck multipliers after sustained sessions.
When enough players on a server hit high combo streaks, it triggers Lucky Weather. This is a server-wide buff that boosts everyone's luck for a limited window. It encourages staying on active servers rather than grinding solo in empty ones.
RNG Ultra Chest
A server-wide boss called the RNG Ultra Chest spawns periodically in a blue cage on the main road. It has 20 billion HP, so you'll need multiple players working together to take it down. Rewards include coins, diamonds, event Dice, and a small chance at limited huge pets exclusive to this event.
Flex Auras
Pets obtained through the Void RNG Event come with special aura effects. These are cosmetic but serve as proof of rarity — other players can immediately see what you've rolled without checking your inventory.
Key Pets & Drop Rates
This update introduces several event-exclusive pets with varying levels of rarity. Here's the full breakdown of what's available and how to get each one.
| Pet | Rarity | How to Obtain |
|---|---|---|
| Titanic Arcane Void Cat | 1 in 3,000,000,000 | Void RNG rolling |
| Titanic Angel Cow | Top 1 reward | Angel Clan Battle (1st place) |
| Gargantuan Wise Cat | Guaranteed | Void Forever pack (paid) |
| Huge Nebula Lion | Uncommon drop | Regular event gameplay |
| Limited Huge Pets | Rare | RNG Ultra Chest drops |
The Titanic Arcane Void Cat is the crown jewel here. At 1 in 3 billion odds, most players will never hatch one naturally. It's designed as a flex piece, and the aura effect reflects that. The Gargantuan Wise Cat from the Void Forever pack is the most accessible high-tier pet this event, but it requires a Robux purchase.
How This Affects Gameplay
The Void RNG Event represents a major shift in how PS99 handles limited-time content. Instead of the usual "hatch eggs in a themed area" formula, this event leans heavily into luck-based rolling with visible streak mechanics. It rewards consistency over raw spending.
For F2P players, the combo streak system is genuinely good news. You don't need gamepasses or premium currency to build streaks — just time and persistence. The Lucky Weather mechanic also means that active servers provide passive benefits you'd miss playing alone.
The Angel Clan Battle adds a competitive layer on top. Clans compete against each other for the exclusive Titanic Angel Cow, which creates a different kind of grind. You'll want an organized clan with active members if you're aiming for that reward.
With over 2,000 pets now in the game, PS99 continues to expand its collection at a rapid pace. The previous Update 77 (Trials & Combine, May 2) already added Time Trials, the Fantasy Combine-o-Matic, and raised the rank cap to 40 with the new Herald rank. Combined with this RNG event, May 2026 is one of the heaviest content months the game has seen.

Updated Tips and Strategies
The Void RNG Event rewards a specific playstyle. Here's how to maximize your results over the next two weeks.
- Join populated servers. Lucky Weather only triggers when multiple players hit high combo streaks, so avoid empty lobbies.
- Don't break your combo. The luck bonus scales exponentially with consecutive rolls. Taking breaks resets your streak, so plan longer sessions when possible.
- Coordinate RNG Ultra Chest attacks. With 20 billion HP, you need server cooperation. Call out spawns in chat and focus fire together.
- Prioritize event Dice from chest rewards. These feed back into the rolling system and compound your overall luck.
- If you're in a clan, communicate for the Angel Clan Battle. Organized clans with scheduled play sessions dominate the leaderboard.
- Save your diamonds for re-rolls during Lucky Weather windows. The server-wide buff stacks with your personal combo bonus for maximum odds.
Previous Update Content Still Active
Update 77's Time Trials are still running alongside the RNG event. You can earn 1-3 guaranteed Huge Pets per day from Trials by racing the clock and breaking objects. The Fantasy Combine-o-Matic also remains available — stack Fantasy Presents through 5 tiers up to Titanic rarity. Don't neglect these while grinding the new event.
Community Reaction
The response to the Void RNG Event has been overwhelmingly positive. Players have been asking for a dedicated RNG zone for months, and Update 78 delivers exactly that. The combo streak mechanic gives a sense of progression even when individual rolls fail, which addresses one of the biggest complaints about pure-RNG systems.
Some criticism has emerged around the 1 in 3 billion odds for the Titanic Arcane Void Cat. A portion of the community feels this crosses into "impossible without exploits" territory. Others argue that's the entire point — it's meant to be legendary, not something everyone owns.
The Angel Clan Battle has energized the competitive scene. Smaller clans are forming alliances and coordinating schedules to compete with established groups. Trading servers are already buzzing with offers for event-exclusive pets, even though the event just started two days ago.
Content creators have been streaming the event heavily, with several achieving high combo streaks live on camera. The Flex Auras add a visual element that works well for stream content, which was likely intentional on BIG Games' part.
