Understanding Steal an Egg Mutated Pets System
In Steal an Egg, mutated pets represent the pinnacle of your collection. These creatures are hatched from eggs stolen across various biomes, ranging from the starting Chicken zone to the end-game Cosmic area. Each pet generates passive income measured in dollars per second, making them essential for upgrading your treadmill speed and expanding your pen.
The core gameplay loop revolves around increasing your treadmill speed to outrun hostile animals, stealing their eggs, and hatching them in your pen. As you progress, you will encounter increasingly bizarre and powerful mutated creatures, from massive golden dogs to invisible bears and cosmic mammoths.
Video Highlights:
- Stealing eggs from 8 different biome zones, each requiring specific speed thresholds
- Hatching a Cosmic King Mammoth from a Prehistoric zone egg
- Encountering Secret T-Rex egg events during night resets
- Using traps and speed gamepasses to outmaneuver aggressive animals
- Discovering that each zone features unique rarity pools
Every time you hatch a new species, check your Pet Index. The game frequently rewards players with cash bonuses and items just for discovering new mutated pets. Claim these rewards regularly to fund your treadmill upgrades.
Pet Rarities and Zone Breakdown
Each zone in Steal an Egg features its own unique pool of mutated pets. As you advance to deeper biomes, the baseline rarity of available eggs increases significantly. A Common pet in the Volcanic zone may easily out-earn a Mythic from the starting area.
| Zone | Recommended Speed | Common Pets | Best Rarity Available |
|---|---|---|---|
| Farm (Chicken) | Starting speed | Chickens, Small Dogs | Epic |
| Desert | ~10,000 | Scorpions, Spiders | Mythic |
| Jungle | ~100,000 | Gorillas, Tigers | Legendary |
| Snow | ~500,000 | Polar Bears, Penguins | Legendary |
| Volcanic | ~1,000,000 | Fire Creatures | Legendary |
| Abyss | ~2,500,000 | Deep Sea Mutants | Cosmic |
| Prehistoric | ~17,000,000 | T-Rex, Mammoths | Cosmic |
| Cosmic | ~700,000,000 | Cosmic Entities | Cosmic |
Always check the recommended speed before attempting to steal from a new zone. If an animal catches you, you lose the egg and get launched into the sky. The game displays the recommended speed near each animal.
The income gap between zones is massive. A Mythic raccoon from the Desert zone might generate only 74 dollars per second, while a Cosmic pet from the Prehistoric zone can produce over 3 million dollars per second. Focus on reaching deeper zones as quickly as possible rather than grinding low-tier eggs.
Top Mutated Pets by Income Generation
Not all mutated pets are created equal. The most valuable companions come from the deepest zones and the highest rarity tiers. Here is a comparison of the most impactful pets you can obtain.
Cosmic King Mammoth
- Rarity: Cosmic (Red Text)
- Source: Prehistoric Zone eggs
- Income: ~3,000,000/sec
- Best overall pet for mid-to-late game
Legendary Polar Bear
- Rarity: Legendary (Gold Text)
- Source: Snow Zone eggs
- Income: ~101,000/sec
- Solid earner before reaching Volcanic
Mythic Tiger
- Rarity: Mythic (Pink Text)

Always use the "Equip Best" button after hatching new pets. This automatically assigns your highest-earning creatures to the active pen, ensuring maximum passive income at all times.
Egg Text Colors and What They Mean
The text color on an egg before hatching indicates its potential rarity. Learning to read these indicators saves time and helps you prioritize which eggs to grow.
| Text Color | Rarity | Estimated Income Range |
|---|---|---|
| White | Common | 10-50/sec |
| Green | Uncommon | 50-200/sec |
| Blue | Rare | 200-1,000/sec |
| Purple | Epic | 1,000-10,000/sec |
| Pink | Mythic | 10,000-500,000/sec |
| Gold | Legendary | 50,000-200,000/sec |
| Red | Cosmic | 500,000-5,000,000+/sec |
Speed Training and Treadmill Upgrades
Speed is the single most important stat in Steal an Egg. Without sufficient treadmill speed, you cannot outrun the animals guarding high-tier eggs. The treadmill upgrade system is straightforward but becomes extremely expensive at higher tiers.
Early Game Speed (0-100,000)
Focus on buying the 2x Money and 2x Growth gamepasses early. Place your starter pets on the treadmill and let them accumulate speed. Upgrade the treadmill whenever affordable. Target the Uncommon and Common speed trails from the Trail Shop for early boosts.
Mid Game Speed (100,000-3,000,000)
By this stage, you should be stealing from the Snow and Volcanic zones. Purchase the Golden Trail for a significant speed multiplier. Continue upgrading the treadmill, which costs roughly 3 billion dollars per level at this range. Let the game idle to accumulate speed passively.
Late Game Speed (3,000,000-25,000,000)
To reach the Prehistoric zone, you need approximately 17 million speed. Invest in the 16x and 32x speed gamepasses (64-160 Robux each). Use the "Grow All Eggs" feature (160 Robux) to instantly mature multiple eggs simultaneously for faster pet turnover.
End Game Speed (25,000,000-700,000,000+)
The Cosmic zone demands a staggering 700 million recommended speed. At this point, every treadmill upgrade provides diminishing returns (plus 80 to plus 100 per step). Consistent idling, maximum gamepasses, and the best available trails are required to progress.
Treadmill upgrades become exponentially more expensive while only providing linear speed increases. A late-game treadmill upgrade can cost billions of dollars for only a marginal speed boost. Plan your purchases carefully.
Trail Shop Speed Boosts
Trails provide passive speed multipliers that stack with your treadmill training. Always purchase the best available trail as soon as you can afford it.
| Trail Name | Cost | Speed Multiplier | Recommended Zone |
|---|---|---|---|
| Common Trail | 1,000 | 2x | Farm |
| Uncommon Trail | 50,000 | 2.5x | Desert |
| Rare Trail | 500,000 | 4x | Jungle |
| Golden Trail | 100,000,000 | 3.5x | Snow/Volcanic |
| Bear Trail | 1,400,000,000 | ~8x | Prehistoric |
Advanced Stealing Tactics
Stealing eggs from aggressive animals requires more than raw speed. Several mechanics and strategies can give you an edge, especially when targeting Secret eggs that spawn during night resets.
Every night cycle, all eggs reset across the map. During this reset, there is a chance for a Secret egg to spawn in a specific zone. The game announces the spawn location (for example, "Secret T-Rex egg spawned in Prehistoric"). Position yourself near the target zone before night falls to claim it first.
Effective Stealing Techniques
- Bait and Switch: If an animal is faster than you, try luring it away from its egg. Some animals will chase you but slow down at the last second, allowing you to circle back and grab the egg while it returns to its post.
- Trap Placement: You receive three bear traps that can be placed on the ground. While they do not fully stop larger animals, they can briefly slow them down, giving you a window to escape with a stolen egg.
- Egg Weight Penalty: Heavier eggs appear to slow your movement speed. If you are barely fast enough to steal from an animal, picking up the largest egg may cause you to get caught. Consider stealing a smaller egg if speed is marginal.
- Server Population: The game does not offer private servers. Other players can compete for the same eggs, especially Secret spawns. Join servers with fewer active players to reduce competition.
The Fuse Machine allows you to combine three identical pets into a single enhanced version with bonus luck. This is useful for clearing pen space while improving your overall hatching fortune. Fuse duplicate pets rather than releasing them.

Frequently Asked Questions
Q: What are Steal an Egg mutated pets and how do I get them?
Mutated pets are hatched from eggs stolen across different biome zones. Each zone features unique pets with varying rarities from Common to Cosmic. To obtain the best mutated pets, you need to increase your treadmill speed to access deeper zones like Prehistoric and Cosmic, then steal eggs from the animals guarding them.
Q: What is the best pet in Steal an Egg?
Cosmic rarity pets from the Prehistoric and Cosmic zones are currently the highest-earning companions. The Cosmic King Mammoth, for example, generates approximately 3 million dollars per second. However, reaching the 700 million speed requirement for the Cosmic zone represents a massive investment of time and resources.
Q: How does the night reset mechanic work?
Every night cycle in the game, all eggs across every zone reset simultaneously. During this reset, there is a chance for a Secret egg to spawn in a random zone. The game announces the spawn location in chat. These Secret eggs typically contain rare or unique pets not available through normal steals.
Q: Can I play Steal an Egg in a private server?
No, the game currently does not offer private servers. This means other players can compete for the same eggs, especially during Secret egg events. To minimize competition, try joining servers with fewer active players or play during off-peak hours.
Q: What does fusing pets do?
The Fuse Machine lets you combine three identical pets into a single enhanced version. The resulting pet retains its species but gains bonus luck, which improves your chances of hatching higher-rarity eggs in the future. This is the best way to manage duplicate pets while gaining a statistical advantage.
Focus on speed above all else. Every progression gate in Steal an Egg is tied to your treadmill speed. Invest in gamepasses early, purchase the best available trails, and let the game idle between active stealing sessions. The jump from 3 million to 17 million speed is the most time-consuming phase, so plan accordingly.
