Pet Simulator 99 continues to evolve, and with each update comes a fresh wave of new pets, items, and challenges. Whether you’re a seasoned player or just hopping into the game, understanding which items hold the most value can give you a serious edge—especially if you’re into trading, leaderboard pushing, or simply flexing your inventory. Based on current trading trends, rarity, and in-game utility, here are the top 10 most valuable Pet Simulator 99 items in 2025.
1. Titanic Banana Pet
Arguably the most iconic and absurdly rare item in the game, the Titanic Banana Pet isn’t just valuable—it’s legendary. Originally released as a joke during a surprise April Fool’s event, this massive, goofy-looking banana quickly turned into one of the most sought-after pets in Pet Simulator 99. Only a tiny number of them were ever distributed, making them extremely scarce. What’s more, it’s a Titanic pet, meaning it offers rideable functionality and powerful stats, giving it real gameplay value on top of its novelty. Because of its rarity, even players with stacked inventories are willing to overpay in trades just to secure one. Owning a Titanic Banana is a flex that few can match.
- Price Trend: This pet has seen consistent upward movement in value since its release, especially as more collectors try to get their hands on the few that exist. As of mid-2025, it’s one of the highest-valued pets on the market, often trading for multiple Titanic or Huge pets combined.
- How to Get/Trade Tip: Direct hatching is no longer possible, so your only shot is through high-end trades. Be prepared to overpay—this is a long-term trophy item. Look for trusted Discord traders or well-known Plaza players to avoid scams.
2. Huge Glitched Crown
This item was introduced during the limited-time Glitch World expansion in early 2025, and its availability was tied to completing a challenging set of quests within a narrow time window. The Huge Glitched Crown has an incredible visual design—it floats, sparkles, and features glitching animation effects that make it stand out in any pet lineup. Beyond aesthetics, it’s a powerhouse in terms of coin multipliers, making it especially useful in high-end farming. Since the Glitch World update was short-lived, not many players earned this pet, and it’s rarely seen on trading boards. Collectors and leaderboard grinders alike are constantly hunting for it.
- Price Trend: Initially stable, but prices spiked sharply after the Glitch World update ended. Its scarcity and visual appeal have made it a core item in high-tier trades.
- How to Get/Trade Tip: Watch for listings from players liquidating old inventories. If you’re holding rare glitch-themed pets, you may be able to negotiate a swap without relying solely on Huge pet value.
3. Rainbow Huge Meebo in a Spaceship
Meebo pets have always had a quirky charm, but the Rainbow Huge Meebo in a Spaceship took things to another level. The original Meebo was released years ago, and the 2025 spaceship variant was introduced as a nod to longtime fans. Getting a rainbow version of this pet requires not just luck, but stacking shiny boosts and multiple hatches—making it extremely hard to obtain. This pet has excellent utility, and its retro-futuristic design, combined with its status as a huge and rainbow pet, places it in the top tier of both casual and competitive collections. Many high-level traders are willing to trade multiple huge pets just to get their hands on one.
- Price Trend: Prices have fluctuated depending on hatch rates and rainbow potion availability, but they’ve trended upward overall, especially with low hatch volume.
- How to Get/Trade Tip: Focus on acquiring the normal Huge Meebo first and consider using rainbow + shiny potions for conversion. In trades, leverage your event pets or multiple Huge pets to negotiate a fair deal.
4. 2025 Anniversary Gift
During Pet Simulator 99’s 2025 Anniversary Event, players were rewarded with special anniversary gift boxes for completing event quests and reaching certain milestones. These gifts could contain ultra-rare pets, such as event-exclusive Huges or signed pets from the dev team. However, many players chose to not open them, betting on their long-term collector value. Today, these unopened Anniversary Gifts are trading at high premiums, especially since the event ended and no more are being issued. The uncertainty around what’s inside, plus the exclusivity of the event itself, makes this item both mysterious and highly desired.
- Price Trend: Value has doubled since the Anniversary event ended. Sealed gifts are now collector items, and their price keeps increasing with time.
- How to Get/Trade Tip: Avoid opening unless you truly need a drop. The unopened version is worth much more. Best strategy: acquire a few while prices are still rising and hold them for future appreciation.
5. Shiny Hologram Axolotl
Shiny pets already carry prestige in Pet Simulator 99, but combining that shiny trait with a limited-edition theme like “Hologram” makes this Axolotl truly exceptional. The Hologram update was only active for two weeks in mid-2025, and it featured several glitchy, see-through variations of popular pets. Among them, the Shiny Hologram Axolotl became the standout due to its animated effects, glowing edges, and enhanced power stats. Players who managed to hatch or convert one during the event found themselves sitting on a goldmine. It’s a favorite in both player showcases and PvE farming teams, making it a high-demand item across casual and pro communities.
- Price Trend: Strong upward trajectory due to the combination of "Shiny" and "Hologram" tags. Prices spiked especially after the Hologram update ended.
- How to Get/Trade Tip: Try to find normal hologram pets and apply shiny scrolls, though success is costly. For trades, combine shiny mythicals and exclusive pets to catch a deal before prices climb again.
6. Exclusive Egg 28
Exclusive Eggs are a cornerstone of Pet Simulator 99’s economy, and Egg 28 stands out as one of the most profitable and coveted in the entire series. Released during a popular limited-time event, Egg 28 featured several high-demand Huge and Titanic pets, including the debut of new variants that haven’t returned since. Players had a limited window to buy these eggs with Robux or through exclusive gift bundles, and once the event ended, the supply became fixed—no more could be added to circulation. Unopened versions of Exclusive Egg 28 are highly valued for their investment potential. Traders often treat them like loot box stocks—some hoard them unopened, while others gamble for a lucky hatch that could earn them triple the trade value. Either way, they’re a hot-ticket item that continues to rise in worth.
- Price Trend: Values rise steadily as unopened eggs become harder to find. Hatched pets still hold value, but sealed eggs are the better investment.
- How to Get/Trade Tip: Avoid hatching unless you’re gambling for a Huge. For resale, keep sealed eggs in pristine condition and watch for limited-egg buyer demand during hype events or updates.
7. Huge Inferno Dominus
Dominus pets have long been a fan favorite in Pet Simulator, and the Huge Inferno Dominus might be the crown jewel of them all. Introduced as part of the Infernal Realms update, this pet came with fiery particle effects, glowing wings, and some of the best base stats among Huge-tier pets. It also had a very low hatch rate—even during the event that featured it—which means only a small portion of players were lucky enough to grab one. Its design appeals to both casual collectors and hardcore traders, and because it’s no longer available through normal gameplay, its scarcity keeps pushing its value higher. The Huge Inferno Dominus is often a deal-clincher in trades involving multiple high-end pets.
- Price Trend: Moderate increase after event closure; holds steady value due to utility and visual design.
- How to Get/Trade Tip: Keep an eye on fire- or Dominus-themed updates—they tend to cause spikes in demand. When trading, highlight both its looks and farming strength to justify premium value.
8. Secret Enchanted Scroll
This unique item isn’t a pet, but its impact on gameplay is huge. The Secret Enchanted Scroll was quietly introduced in late 2024 as part of a hidden questline and can be used to permanently enhance a pet’s special ability or unlock a second enchantment slot—something that’s otherwise unattainable. Because of its utility and extremely low drop rate (often requiring a full week of grinding certain dungeons), it’s become one of the most in-demand items for serious players. High-level traders view it as a power item, not just a cosmetic or collector’s piece. Players seeking leaderboard positions or optimized farming teams are constantly hunting for scrolls, which keeps the demand and value high in 2025.
- Price Trend: Gradual but solid rise due to ongoing demand from competitive players. Rare and not flashy, but functional value drives the price.
- How to Get/Trade Tip: Grind dungeon quests during special boosts or events. In trading, target players trying to optimize top-tier pets—they’re willing to trade shinies or exclusive pets for scrolls.
9. Developer Companion 5
Few items in the game are as exclusive as the Developer Companion series, and Companion 5 is the rarest of the bunch. These pets are distributed manually by developers to select players—typically streamers, event winners, or longtime community contributors. There’s no way to hatch, buy, or craft this pet. It’s a true status symbol, often carrying a unique “signed by dev” tag and featuring a custom animation or texture. Even among whales and top-tier collectors, Developer Companion 5 is seen as one of the ultimate trophies. Because it’s so rare, there’s very little market activity around it—when one does show up in a trade, it causes a stir in the entire community.
- Price Trend: Almost no public trades; when one appears, it demands insane overpays. It’s more a prestige symbol than a market item.
- How to Get/Trade Tip: You likely won’t find this unless you know someone directly. If you’re offered one, verify its authenticity carefully—fake developer tags exist. Never trade outside trusted platforms.
10. Huge Lucky Block Mimic
The Lucky Block event was a nostalgic hit that brought back a classic mechanic from earlier versions of Pet Simulator. During this event, players could break colorful Lucky Blocks scattered across the world, with a small chance of spawning the Huge Lucky Block Mimic. This pet was modeled after the blocks themselves, with a shiny gold texture and playful jumping animation. What makes this item valuable isn’t just the event tie-in, but also its drop mechanics—players had to grind hundreds of blocks, with no guarantee of a spawn. It also had a very low catch rate, and the event only lasted a few days. Today, the Huge Lucky Block Mimic is both a conversation piece and a trading powerhouse, especially for collectors who love event exclusives.
- Price Trend: Spike during the event, then a stable high price post-event. Demand rises every time “Lucky Block” is referenced or teased in leaks.
- How to Get/Trade Tip: Keep this in your inventory during event season—it becomes twice as desirable during reruns or nostalgia events. For trades, time your listings to coincide with hype moments.
