Pet Simulator 99 Update June 2026 — The BACKROOMS Returns

By Earnaldo Team • June 14, 2026 • 9 min read

Pet Simulator 99 dropped Update 80 on Saturday, June 13, 2026, and it reopens one of the game's most requested areas: the Backrooms, reimagined this time as a party-themed zone called Level Fun. The event runs for two weeks, ending Saturday, June 27, 2026, and packs in a fresh wave of Huge and Titanic pets, new bosses, and hidden secrets to chase.

What's New in the BACKROOMS Update

The headline is the return of the Backrooms dimension, but it's not the same liminal maze longtime players remember. BIG Games rebuilt it as Level Fun — a recognizable slice of Backrooms lore where the endless yellow halls are decked out with balloons, streamers, and party lights. The contrast between the creepy setting and the celebration theme is the whole point, and it gives the zone a look unlike anything else in the game.

The pet pool is where most players will spend their attention. The chase pet sitting at the top of the rarity ladder is Gargantuan Guest 666, the rarest drop in the event. Below it sit a set of Titanic and Huge pets pulled straight from the Backrooms theme.

Alongside those named pets, the update adds Huge Piggy Piggy and Huge Partygoer Cat, plus a run of 10 Warped pets — the corrupted, alternate-texture variants that have become a staple of recent events. Warped pets carry higher stats than their standard counterparts, so they're worth targeting if you can afford the extra rolls.

The zone also brings new bosses and a handful of secrets tucked into Level Fun's layout. Boss fights drop event currency and feed into the rewards track, which is the main way you'll work toward the Titanic and Gargantuan unlocks before the event closes.

How This Affects Gameplay

Backrooms events have always been about RNG grinding under a deadline, and Update 80 is no different. You've got a two-week window to hatch the new eggs, beat the bosses, and bank enough rewards to claim the chase pets. Once June 27 hits, the area closes and the event-exclusive pets stop being obtainable through normal play.

If you care about your damage output, the new Titanic pets are a real step up. Titanic-tier pets in Pet Simulator 99 sit a full bracket above Huge pets in raw strength, so even one Titanic Partygoer Cat or Titanic Piggy Piggy can shift how fast you clear high-tier worlds. The Gargantuan Guest 666 is the dream pull, but realistically most players will measure success by how many Huge and Warped pets they walk away with.

Enchant strategy matters more during limited events. Running Ultra-Shiny and high-tier luck enchants while the Backrooms eggs are live stretches every diamond you spend, since you can't come back for these specific eggs later. Plan your enchant slots around the event before you start dumping currency into hatches.

Trading value is the other angle to watch. Limited event pets tend to climb in worth once the area closes and supply is locked, so a spare Titanic Partygoer Cat or Warped variant you don't need for your team can hold real trade value later. With reports that updates are slowing down, this particular batch of Backrooms pets may end up scarcer than usual — another reason to grind hard before June 27.

New Codes

Pet Simulator 99 handles rewards through its in-game code system rather than text codes tied to each individual update, and no new event-specific codes shipped alongside the Backrooms launch as of June 14, 2026. Your best move is to check the in-game code shop and our regularly updated Pet Simulator 99 codes page, where we track every working reward as it goes live.

If you're hunting free Diamonds to fund event hatches, the codes page is the first place to look before you spend Robux.

Updated Tips and Strategies

Prioritize the eggs before the bosses

Hatching is variance-heavy, so the earlier you start rolling the Backrooms eggs, the more chances you give yourself at a Titanic or Warped pull. Boss rewards are more predictable and accumulate steadily, which means they're easier to finish in the back half of the event. Front-load the gambling, back-load the grind.

1. Stock up on Diamonds first — redeem codes and clear daily rewards before you hatch
2. Slot luck and Ultra-Shiny enchants before opening any Backrooms eggs
3. Roll the new eggs early while your enchant boosts are active
4. Farm the Level Fun bosses for event currency between hatch sessions
5. Spend banked rewards on the Titanic and Gargantuan unlocks before June 27

Don't sleep on the secrets

Level Fun hides several secrets in its layout, and past Backrooms events rewarded players who explored off the obvious path. Take a few minutes to walk the zone fully before you settle into a pure hatch-and-farm loop. The detours often pay out more than the grind.

Community Reaction

The Pet Simulator 99 community greeted the Backrooms return with a mix of excitement and nostalgia. The Backrooms theme has been a fan favorite since earlier events, and turning it into the party-styled Level Fun gave the rerun enough of a twist to feel fresh rather than recycled.

That said, the bigger conversation has been about the game's future. Players have widely circulated reports that BIG Games is winding down major development on Pet Simulator 99, pointing to the studio shifting attention toward new projects. Many are treating Update 80 as one of the last big content drops, which has added urgency to the grind — nobody wants to miss a limited pet if updates really are slowing down.

Reaction to the pets themselves has been strong. Gargantuan Guest 666 in particular has players hooked, since Gargantuan-tier pets are rare enough that landing one is a flex worth showing off. The Warped variants have also drawn interest from collectors who chase the highest-stat versions of every event pet.
