Godzilla Requirements at a Glance
| Item | Cost | Details |
|---|---|---|
| Ethereal Belt | $5 trillion or 10,999 Robux | Endgame conveyor belt required |
| Godzilla Egg | $68 billion | 100,000x luck, 2nd rarest egg |

| Best Mutation | Snow variant | Highest money per second |
| Gold Boost | 720% | From Ethereal Belt unlock |
What Makes Godzilla Special?
Godzilla is currently the rarest pet you can unlock in Build a Zoo, obtained from the Godzilla Egg introduced in Update 28. Unlike standard pets, Godzilla can get every mutation in the game, with the Snow mutant generating astronomical earnings per second—perfect for AFK grinding.

The Ethereal Belt that spawns Godzilla Eggs also grants 720% increased gold earnings, making it a game-changer for endgame progression. This isn’t just about collecting—it’s about fundamentally transforming your zoo’s earning potential.
Step-by-Step Unlock Process
Step 1: Reach Endgame Status
You can’t skip progression. Unlock every conveyor belt up to the Unicorn Belt (second-best). The Ethereal Belt won’t appear until you’ve completed this grind. Focus on upgrading systematically rather than rushing.
Step 2: Purchase the Ethereal Belt
Open the conveyor menu and upgrade to the Ethereal Belt. You’ll need $5 trillion in-game currency—or shortcut with 10,999 Robux if you’re impatient. This belt is the only way Godzilla Eggs spawn, so there’s no alternative path.
Step 3: Farm Currency While Waiting
The Godzilla Egg is quite rare and costly since it has 100,000x luck. Keep collecting cash from your existing pets while monitoring the conveyor. Set up your zoo for maximum AFK efficiency—this could take hours or days depending on luck.
Step 4: Secure $68 Billion
When the Godzilla Egg finally spawns, you’ll need $68 billion ready immediately. Miss your window and you’ll wait for the next spawn. Stack your earnings beforehand to avoid heartbreak.
Step 5: Hatch and Optimize
Place your egg on your base and wait approximately two hours. Use luck potions during hatching to increase your odds of getting Godzilla instead of common variants. The Snow mutation is your ultimate goal—prioritize this for maximum profit.

Pro Tips for Faster Progress
Maximize Belt Upgrades
Every conveyor belt level increases your gold earning percentage. Don’t neglect early upgrades—compound growth matters more than you think. Each successive belt enhances your entire zoo’s passive income generation.
Stack Luck Potions Strategically
Don’t waste potions on common eggs. Save them for when you’re hatching the Godzilla Egg specifically. Multiple luck potions stack multiplicatively, dramatically improving your chances of getting the legendary pet instead of lower-tier variants.
AFK Grind Efficiently
The game can store cash only for 24 hours. Leave your game running overnight but collect earnings daily. Set reminders—uncollected currency beyond 24 hours is wasted progress.
Upgrade Big Pets First
Feed your big pets to level them up. Higher-level big pets generate significantly more money per second, accelerating your path to the $5 trillion Ethereal Belt and $68 billion egg thresholds.
Alternative: The Robux Route
Not everyone has time to grind trillions. Spending 10,999 Robux on the Ethereal Belt bypasses weeks of progression. If you’re serious about competitive Roblox gaming and have the budget, this shortcut makes sense.
However, you’ll still need $68 billion for the egg itself—no Robux shortcut exists for that purchase. Balance paid progression with smart grinding.
Common Mistakes to Avoid
Ignoring Fish Deck
Fish eggs provide steady income that complements terrestrial pets. Don’t neglect your fishing deck progression—it’s passive income that adds up.
Selling High-Value Pets Too Early
Resist the temptation to liquidate big pets for quick cash. Their long-term earning potential exceeds their sell value exponentially. Patience pays.
Missing Spawn Windows
With 100,000x luck requirements, Godzilla Eggs spawn infrequently. Check your conveyor regularly when you’re in the billion-dollar range. Set up your device for notifications if possible.
Is Godzilla Worth It?
Absolutely—if you’re committed to endgame content. The Snow-mutated Godzilla generates enough money per second to fund multiple Ethereal Belt-tier purchases. It’s the ultimate passive income machine.
For casual players, the grind might feel excessive. But for completionists and AFK grinders, Godzilla represents Build a Zoo’s pinnacle achievement.

FAQs
Q: Can I get Godzilla from any conveyor belt besides Ethereal?
A: No. The Godzilla Egg exclusively spawns from the Ethereal Belt, which is the endgame conveyor added in Update 28. You must unlock this specific belt first—there are no shortcuts or alternative spawning methods.
Q: What happens if I can’t afford the Godzilla Egg when it spawns?
A: The egg will eventually disappear from the conveyor as new eggs cycle through. You’ll need to wait for it to spawn again, which could take considerable time given its 100,000x luck requirement. Always maintain $68 billion in reserves once you unlock the Ethereal Belt to avoid missing opportunities.
