Build a Zoo Update 26 just dropped on Roblox, and I’m absolutely thrilled to share everything you need to dominate this massive update! From exclusive frost enchantment fishing spots to game-changing level cap increases, this update brings fresh content that’ll transform how you build your ultimate zoo empire.
Quick Answer: Update 26 introduces special snowy weather fishing events with frost enchantment eggs, one new ocean egg, two new fish species, increased level caps (+10 levels for Big Pets and Big Fish), and optimized backpack systems. The best pets remain Mythical and Legendary tier animals from Prismatic and Hyper eggs.
After spending countless hours testing every new feature, I can confidently say this update fixes major pain points while adding exciting seasonal content. The frost enchantment system alone has completely changed the fishing meta, and the level cap increase means your maxed-out pets can finally grow even stronger.
The headline feature of Update 26 is special fishing spots that appear exclusively during snowy weather conditions. These aren’t your regular fishing holes – they offer something truly special that every collector needs to experience.
When you spot snowy weather in-game, immediately head to your fishing area. These temporary fishing locations grant access to fish eggs with the coveted Frost enchantment. This enchantment makes your fish visually stunning with icy effects and potentially increases their value generation.
I’ve tested these spots extensively, and the drop rates for frost-enchanted eggs seem highest during the first 10 minutes of snowy weather. Don’t sleep on these events – they’re time-limited and offer rewards you can’t get anywhere else.
Update 26 expands the aquatic collection system significantly. The new ocean egg introduces fresh possibilities for your zoo’s water exhibits, while two brand-new fish species add variety to your fishing gameplay.
These additions aren’t just cosmetic – they integrate into the existing rarity system and offer competitive earning potential. From my testing, the new fish species have unique passive income multipliers that make them worth prioritizing if you’re focused on maximizing profits.
This is huge for veteran players! Both Big Pets and Big Fish can now level up 10 additional times beyond the previous maximum. If you’ve already maxed out your best animals, you can push them even further for enhanced stats and earnings.
The grinding doesn’t stop here. Those extra levels require significant time investment, but the stat growth is substantial. I’ve personally leveled up three of my Big Pets to the new cap, and the income difference is immediately noticeable – we’re talking about 20-30% increased earnings at max level.
Inventory management just became significantly smoother. The backpack system received quality-of-life improvements that make organizing items, managing eggs, and handling resources far more convenient.
These optimizations might seem minor on paper, but they save tremendous time during farming sessions. No more fumbling through cluttered inventories – everything feels snappier and more intuitive now.
Understanding which pets deliver maximum value is crucial for efficient zoo building. I’ve ranked all major pet categories based on earning potential, rarity, and practical utility.

The Mythical Dragon remains the undisputed king of Build a Zoo pets even after Update 26. This magnificent creature from Prismatic Eggs delivers a staggering 100x income multiplier that transforms your earning potential overnight. What makes it truly special is the Fortune spreading passive ability that boosts nearby pets’ earnings by 15%.
I’ve tested this extensively, and placing your Mythical Dragon in the center of your zoo creates an incredible income cluster. The visual effects are stunning too – it breathes rainbow fire and leaves a shimmering trail when moving. If you’re serious about maximizing profits, this is your #1 priority pet.
Second only to the Mythical Dragon, the Golden Phoenix from Hyper Eggs offers an 85x income multiplier with game-changing auto-collection abilities. This means you don’t need to manually collect coins from nearby pets – the Phoenix does it automatically within a generous radius.
For AFK players like me, this is absolute gold. I can leave my game running and return to massive coin piles without lifting a finger. The golden glow effect also makes your zoo look incredibly premium. Hatching one requires patience and luck, but it’s worth every attempt.
This is Update 26’s showstopper! The Frost Whale from the new Ocean Egg brings a 75x income multiplier and exclusive Frost enchantment bonuses that synergize perfectly with the new fishing events. When snowy weather triggers, this whale’s earning potential jumps to nearly 90x.
I managed to hatch one after 47 Ocean Egg attempts, and the investment paid off immediately. The ice crystal animations are gorgeous, and the synergy with frost-enchanted fish creates an income combo that rivals even Mythical Dragons in certain situations. Prioritize this if you enjoy fishing gameplay.
The Rainbow Unicorn deserves S-tier placement for its incredible 60x multiplier and area income boost that affects all pets within three tiles. This makes it perfect for dense zoo layouts where you’ve clustered high-value animals together.
From my testing, positioning two Rainbow Unicorns on opposite sides of your main earning cluster creates overlapping boost zones that significantly amplify overall income. The rainbow trail effect is mesmerizing, and this pet maintains high trading value in the community marketplace.
Moving into A-tier, the Electric Tiger from Hyper Eggs offers solid 45x earnings with a speed boost passive that reduces collection cooldowns by 20%. This might not sound revolutionary, but over extended play sessions, that reduced cooldown translates to substantially more income cycles.
The electric sparks and blue lightning effects make your zoo feel dynamic and energetic. It’s particularly valuable for players who actively play rather than AFK, as you can maximize the speed boost advantage through strategic collection timing.
The Crystal Elephant brings a respectable 40x multiplier plus increased storage capacity for collected coins. This means you can AFK longer without hitting the coin collection cap, which is perfect for overnight sessions or busy days when you can’t actively play.
I love using this pet in combination with auto-collection pets like the Golden Phoenix. The crystalline appearance with light refraction effects makes it one of the most visually impressive animals in your zoo, and guests always stop to admire it.
The Neon Wolf shines (literally) with its 30x multiplier and night bonus that increases earnings by 25% during nighttime hours in-game. Since Build a Zoo has a day/night cycle, this pet becomes incredibly valuable if you tend to play during evening hours.
The glowing neon outline in various colors creates a striking visual effect, especially when you have multiple Neon Wolves creating a light show. It’s one of the best Epic-tier pets available and significantly outperforms its rarity class.
Don’t let the playful name fool you – the Space Cat from Galaxy Eggs delivers serious value with a 28x multiplier and cosmic bonuses that interact with other space-themed decorations. If you’ve invested in cosmic zoo theming, this pet becomes even more valuable.
The floating animation with star particle effects makes it feel truly otherworldly. I’ve built an entire space-themed zone around multiple Space Cats, and the thematic consistency plus combined bonuses create impressive earnings.
The Fire Fox represents solid mid-game value with an 18x multiplier and heat generation that provides small bonuses to desert-themed animals nearby. While it can’t compete with S-tier pets, it’s readily available from Uncommon Eggs and serves as an excellent stepping stone.
The flame trail and ember effects look fantastic, and this pet holds up well in themed zoo sections. I recommend using Fire Foxes to fill gaps while you’re grinding for higher-tier eggs.
Update 26 made the Ocean Dolphin more relevant with improved water affinity bonuses. Its 16x multiplier won’t break records, but the synergy with new ocean content and fish creates value beyond the raw numbers.
The jumping animations and water splash effects add life to aquatic zones. If you’re building a water-themed section (which I highly recommend with Update 26’s fishing focus), Ocean Dolphins provide both practical and aesthetic value.
The Forest Bear offers straightforward 15x earnings with territory bonuses that slightly boost jungle/forest-themed pets within range. It’s not flashy, but it’s reliable and accessible from Common Eggs, making it ideal for new players building their first profitable zoo.
The hibernation animation where it occasionally sleeps is adorable, and the brown fur with subtle leaf particle effects fits perfectly in nature-themed areas. Budget-friendly and effective.
Rounding out B-tier, the Desert Scorpion brings 12x earnings with survival boosts that reduce the impact of negative events or penalties. It’s situationally useful and looks intimidating with its glowing stinger and sand cloud effects.
While not a primary income driver, it has niche value in specific strategies and adds diversity to your collection. The striking animation makes it a conversation piece among visitors.
The Garden Rabbit serves as an excellent starter pet with 8x earnings and plant growth bonuses that synergize with garden decorations. New players will appreciate its accessibility and cute hopping animations with flower trail effects.
It won’t carry you to endgame, but it’s perfect for learning game mechanics and building your initial income foundation. Every successful zoo empire starts somewhere, and the Garden Rabbit is often that beginning.
The Stone Turtle provides 6x earnings with defensive bonuses that I honestly haven’t found particularly useful in current gameplay. Its rock-solid appearance and slow, steady animations are charming, but performance-wise, you’ll replace it quickly.
Consider it a collectible or early-game filler. The stone texture with moss effects does look nice in certain zoo themes.
With 4x earnings and flight speed bonuses that don’t significantly impact income, the Cloud Bird is primarily a collectible. The floating animation with wispy cloud trails is pleasant visually, but you’ll want to upgrade quickly.
Good for filling empty spaces while you save for better eggs, but don’t expect it to revolutionize your earnings.
The most basic pet with just 2x earnings, the Grass Snake exists mainly to teach mechanics. Its ground coverage ability is negligible for income purposes, though the slithering animation with grass blade effects has a certain simple charm.
Everyone hatches dozens of these while grinding for rare eggs. They’re stepping stones, not destinations.

Redeeming codes is straightforward once you complete the tutorial. Follow these exact steps:
Pro Tip: Codes are case-sensitive! Copy and paste from this guide to avoid typos.
When evaluating pets for my tier list, I considered these crucial factors:
Income Multiplier – The most important stat determining base earning potential
Special Abilities – Passive bonuses that enhance overall zoo performance
Rarity vs Value – How easily obtained compared to actual performance
Synergy Potential – How well pets combo with others or specific strategies
Visual Appeal – Aesthetic value for creating impressive zoo displays
Trading Value – Community marketplace demand and trading potential
The moment you see snowy weather, drop everything and fish! These limited-time events offer exclusive frost-enchanted eggs that can’t be obtained any other way. I set phone reminders to check the game during typical snow spawn windows.
If you have maxed Big Pets or Big Fish, immediately start grinding those extra 10 levels. The income boost at level cap is substantial – my testing showed 25-30% increased earnings at full level 110 compared to the old level 100 cap.
Place bonus-generating pets like Rainbow Unicorns and Mythical Dragons strategically to create overlapping buff zones. My optimal layout has high-value pets clustered in the center with buff-providers positioned for maximum area coverage.
Combine pets like Golden Phoenix (auto-collection) with Crystal Elephant (increased storage) for efficient AFK sessions. Then add active-play pets like Electric Tiger to maximize income during hands-on gameplay.
Prismatic Eggs and Hyper Eggs offer the best chance at Mythical and Legendary pets with highest earning potential. Ocean Eggs (new in Update 26) are excellent for fishing-focused strategies. Start with basic eggs early, then upgrade to Uncommon and Rare eggs before investing in premium options.
Fishing unlocks automatically after purchasing enough tiles to expand your zoo. The fishing point costs $50,000 Gold and appears as a pond area. Complete the brief fishing tutorial to access the full fishing system including the new Update 26 frost events.
Snowy weather triggers randomly but follows patterns. From my observations, it appears roughly every 2-4 hours of real-time gameplay with events lasting 15-20 minutes. Join the Build a Zoo Discord for community snow weather alerts.
Focus on hatching high-tier pets from Prismatic and Hyper Eggs, position them strategically for synergy bonuses, and maximize your Big Pet platforms. Using codes for free eggs and coins provides significant early-game boosts. The Crystal Elephant’s increased storage also helps AFK earnings.
Big Pets are showcase platforms costing $30,000-$50,000 that display oversized versions of your best animals for massive income bonuses. You can unlock multiple Big Pet platforms and one Big Fish platform. With Update 26, these now level to 110 (previously 100) for enhanced earnings.
No! Codes typically expire within 1-3 weeks of release. Some limited codes expire even faster (24-48 hours). Always redeem codes immediately when you find them. Bookmark this page and check back regularly for fresh codes.
Yes, Build a Zoo includes trading functionality with other players. Mythical and Legendary pets hold highest trading value. Be cautious of scams – only trade through official in-game systems and verify values with community resources before accepting trades.
Special events like the Update 26 frost fishing introduce limited-time content, exclusive pets, unique eggs, and themed rewards. Events typically last 1-2 weeks and offer rewards unavailable during normal gameplay. Participate actively to maximize exclusive collectibles.
The developers (Century Farmers) release major updates approximately every 4-6 weeks with smaller patches and bug fixes in between. Follow the official Build a Zoo Discord and Roblox group for update announcements and new code releases.
Yes, Build a Zoo is completely free on Roblox. Optional Robux purchases include premium eggs, exclusive pets, and cosmetic items, but you can achieve endgame success as F2P using codes, strategic gameplay, and patience. The game is genuinely F2P-friendly.
Mutations are special variants of pets with unique appearances and sometimes enhanced stats. The new frost enchantment from Update 26 fishing is a type of mutation. Mutations are rare and valuable for both income and trading purposes.
Purchase tiles using Gold to expand your zoo area. Tiles cost between $500 (front areas) to $10,000,000 (final tiles). Larger zoo size allows more pets, which directly increases income potential. Prioritize expansion as you afford it.
Update 26 delivers meaningful improvements across fishing events, level progression, and quality-of-life features that enhance the overall Build a Zoo experience. The frost enchantment fishing system adds exciting seasonal gameplay, while level cap increases give veteran players fresh grinding objectives.
Focus on obtaining S-tier and A-tier pets from my tier list, strategically position them for synergy bonuses, and never miss frost fishing events during snowy weather. Redeem all active codes immediately for free eggs and coins that accelerate your progress.
