Pet Simulator 99 Update 77 — Fantasy World, Time Trials & TITANIC Presents Guide (May 2026)

Last Verified: May 4, 2026. Update data sourced from BIG Games' official update post at biggames.io/post/pet-simulator-99-update-77, published May 2, 2026.

Pet Simulator 99 Update 77 landed on May 2, 2026, and it's one of the more content-dense drops in recent memory. The headline is a full new event zone — the Fantasy World / Veilwood Hollow — with nine mystical pets including what BIG Games calls the game's strongest pet, the Wicked Kirin. Alongside the event, the update ships a competitive Time Trials mode, a multi-tier present-crafting mechanic called the Fantasy Combine-o-Matic, the Infinity Egg, and an expansion to Rank 40.

If you played through the PS99 Spring Egg Machine event in April, this update is a bigger ask — but it's also worth more. Here's every feature, how they work, and what to prioritize.

TL;DR — Update 77 at a Glance

Fantasy World Event — Veilwood Hollow

The Fantasy World is the centerpiece of Update 77. It adds Veilwood Hollow — a new zone with misty grove environments and ancient castle ruins. Progress through Veilwood Hollow to unlock access to the Hollow Veil Castle zone, the event's deeper area.

The zone introduces nine new mystical pets. The top of that roster is the Wicked Kirin, which BIG Games identifies as the game's strongest pet at this update's release — though "strongest" in PS99 context typically refers to raw stat output for the pet's primary use case. These pets are event-limited, meaning they won't be accessible from normal gameplay after the Fantasy World event ends.

If you're chasing the Wicked Kirin specifically, understand the rarity context: it's a prestige-tier pet in an event zone, which means demand will spike during the event window and again after the event closes when existing copies are the only supply. Trading for it mid-event is typically more expensive than post-event, but post-event supply is also frozen.

For reference: our PS99 Huge & Titanic Pets database and Eggs & Hatch Rates page are sourced from BIG Games' official API and will update when the Fantasy World pets are added to the API roster.

TITANIC Presents — Fantasy Combine-o-Matic

The Fantasy Combine-o-Matic is a new crafting mechanic tied to the Fantasy World event. It lets you stack presents across five ascending tiers:

1. Small Present
2. Medium Present
3. Large Present
4. Huge Present
5. Titanic Present → rewards Titanic Ruinous Angelus

Each tier requires combining multiple presents from the tier below — the exact combine ratios haven't been officially published in detail, but the pattern is consistent with previous PS99 crafting mechanics (typically 3–5 of the lower tier per combine). The Titanic Ruinous Angelus at the top is a Titanic-tier pet, and the entire chain is designed to be a mid-to-end game progression target for the event's duration.

Strategy note: Don't sell your small presents thinking they're worth more immediately. The combine chain rewards compound — a Titanic Present is worth considerably more than the sum of five Large Presents sold individually, and the Titanic Ruinous Angelus commands a premium during the event window when supply is still limited. If your account can sustain the grind, completing the chain is the higher-value play.

Time Trials — Competitive Mode Explained

Time Trials is the first permanent competitive mode addition in Update 77. Unlike events (which end when the timer hits zero), Time Trials is a lasting feature of the game.

How it works:

• Players race through competitive waves of breakables and boss chests — the same breakable mechanic from normal gameplay, but structured as a timed challenge
• 48-hour leagues: seasonal competitive pools with a two-day window, so the top of each league resets every 48 hours
• Daily solo leaderboards: individual performance tracked per day, separate from the league standings

Time Trials rewards leaderboard placement rather than just participation. Expect the leaderboard format to evolve as BIG Games sees how the community engages — top Roblox developers routinely tune competitive modes in the first few weeks based on queue times and participation patterns.

For players who have been end-game or near-cap for a while, Time Trials is the first repeatable challenge that meaningfully tests your pet setup rather than just grinding more breakables.

Rainbow Shiny GARGANTUAN Leaderboard

Update 77 also adds a Rainbow Shiny GARGANTUAN leaderboard running on the same 48-hour league format. This one tracks who has obtained Rainbow Shiny Gargantuans — the rarest modifier tier on the rarest pet tier — within each league window. It's primarily a flex leaderboard for players who are actively hunting Gargantuans, but it also signals BIG Games' intent to make Gargantuan-tier pets a competitive long-term target rather than just a collection milestone.

Infinity Egg — Every Egg, Unlocked

The Infinity Egg is one of the more quietly useful additions in Update 77. Located at the Fantasy World spawn, it lets you hatch any egg you've previously unlocked from Worlds 1–4 — all from a single access point.

This is primarily a convenience feature for accounts that want to continue targeting specific pets from older world eggs without navigating back to those worlds. For players working through the egg hatch rate database, this also means you can more efficiently run targeted hatching sessions on any specific pet you're chasing — find the egg that hatches it, confirm it's from Worlds 1–4, and run it from Fantasy spawn.

The Infinity Egg doesn't change the underlying hatch rates — it's access, not a boost. The probability of hatching any specific Huge or Titanic remains exactly what the egg's pool weights show.

Rank 40 Expansion — New Cap & Rewards

Update 77 raises the Rank cap with five new ranks, extending progression to Rank 40 — Herald. The new ranks come with new loot thresholds:

If you were already at the previous rank cap, these new ranks are your immediate next target. The T11 Damage Potion in particular is a meaningful upgrade for breakable farming speed, which directly feeds into Time Trials performance.

Trading Terminal Upgrade

The Trading Terminal has been relocated to the Super Computer — a QoL change that consolidates two frequently-used features into one UI location. The more useful addition is drag-delete functionality: you can now drag items to remove them from trades in progress rather than clicking through confirmation dialogs.

It's a small change but a meaningful one for high-volume traders. The old flow required more clicks per unwanted item during active trade negotiation; drag-delete speeds up the per-trade setup time noticeably.

Cosmic Values RAP Toggle

Update 77 adds a settings toggle to display Cosmic Values RAP (Recent Average Price) directly in your PS99 inventory. If you have Cosmic Values connected, enabling this surfaces RAP numbers alongside your pets in-game — no more tabbing out to check values during trades.

A note on RAP: Cosmic Values RAP reflects recent trade history, not necessarily what a pet will trade for in your next trade. Treat it as a reference floor/ceiling, not a hard price. Fresh event pets (like the Wicked Kirin right now) will have volatile RAP data for the first few weeks as trading volume establishes a consensus. Our PS99 hub has full Enchants & Charm data and hatch rate info — we don't publish trade values for the same reason the RAP itself fluctuates: accuracy requires an active market, not a static list.

What to Do First in Update 77

Given everything in the update, here's a prioritized action list by account level:

New/Mid-Game Accounts

1. Rank grind — if you're below Rank 35, the new ranks give meaningful rewards. Golden Prison Key opens endgame content; T11 Damage Potion accelerates your farming speed.
2. Infinity Egg — if you're targeting a specific Huge from a World 1–4 egg, the Fantasy spawn access point is now your most convenient path.
3. Small/Medium Present stacking — even mid-game, starting the Combine-o-Matic chain is worth it. Don't sell your presents until you understand the chain value.

End-Game / Prestige Accounts

1. Fantasy World / Wicked Kirin — this is your flagship target for the event window. Supply is limited to the event's run.
2. Time Trials — test your pet setup competitively. 48-hour leagues mean your first few runs are about calibrating, not expecting a top finish.
3. TITANIC Presents full chain — if you have the volume to run the combine to Titanic Present, the Titanic Ruinous Angelus is the highest-value item in the update for post-event trading.
4. Rainbow Shiny GARGANTUAN leaderboard — if you're actively hunting Gargantuans, the leaderboard now adds a competitive layer to something you're already doing.
