Steal an Egg wiki: 265 pets, the eggs, zones and mutations — with the numbers

The official description on the Roblox page lists the whole game in seven lines: steal eggs from pets; hatch eggs to collect rare pets; earn money from your pets; upgrade your treadmill and base; train on the treadmill to gain speed; steal eggs from other players; discover rarer eggs, pets, sizes and mutations. It also confirms the game runs on desktop, console, mobile and tablet, and that servers hold a maximum of seven players.

That last number matters more than it looks. Seven players per server means every nest you see is contested by at most six other people, and every pen you fill is a target for the same six. Most of the strategy on this site — which zone to farm, how many bear traps to lay, when to sit on a pen and when to go steal — follows from that seven-player ceiling.

The genre tag is Simulation › Tycoon. In practice it plays like a chase game wrapped around an idle economy: the running and dodging is what you do with your hands, and the income per second is what happens while you are doing it.

Everything below is documented on the community wiki's Eggs and Biomes pages and matches the official description. Eggs sit in nests inside zones. Each zone has its own set of eggs — eight in every normal zone — and nests reset every five minutes, so a zone you have just emptied refills on a short timer.

A guardian sleeps next to the nests. You walk up, take an egg, and run. Bigger eggs are worth more but are heavier, which slows you down; the wiki is explicit that having enough speed to enter a zone does not mean you have enough speed to get back out with a large egg. Speed is trained on the treadmill at your base and can be multiplied with Robux boosts.

Back at the base the egg goes into a pen and grows for a fixed time — ten seconds for a Forest Chicken, eighteen hours for the Angels & Demons World Burner — then hatches into a pet that pays money every second. Money buys better pens, treadmills and trails; speed opens the next zone; the next zone has better eggs. Other players can walk into your base and take an egg out of your pen, which is why the game is called what it is.

The wiki's pet database uses eleven rarity labels — Common, Uncommon, Rare, Epic, Legendary, Mythic, Cosmic, Secret, Eternal, Divine and Event — plus Monster, which in our table covers twelve event pets. Across the 265 pets in our table, the base income spread between the bottom and the top of the ladder is roughly ten orders of magnitude: a Forest Chicken lists $1/s, the Enchanted Forest's Spirit World Guardian lists $26B/s on its own page (the wiki's pet data module lists $15B/s).

The table below uses the wiki's own infobox values, quoted as listed, and counts how many pets sit in each tier. Base income is for a normal-size pet with no mutation; the mutations page explains how the multipliers stack on top.

Roblox publishes, for every badge, the percentage of players who earned it in the past day. Steal an Egg has six badges. On 13 September 2026 the 'WELCOME!' badge sat at 7.8 %. 'Hatched Secret!' was at 3.4 %, 'Hatched Eternal!' at 1.7 %, 'Divine Trail!' at 1.0 %, 'Hatched Divine!' at 0.8 % and 'Angelic Treadmill!' at 0.5 %.

Those figures describe a single day's players: they do not say how many players own a Divine or the top treadmill, and none of them is a hatch chance.

There are eleven zones on the normal route and a twelfth, Angels & Demons, added to the wiki on 12 September 2026. Each has a speed requirement and a guardian. Forest has no gate and a Chicken; Lake needs 900 speed and is guarded by a Swan; Desert needs 10K (Scorpion); Jungle 40K (Tiger); Snow 170K (Yeti); Volcano 700K (Cerberus); Abyss Ocean 2.5M (Moby); Prehistoric 18M (T-Rex); Cosmic 700M (Cosmic Skeleton); Cherry Blossom 2.5B (Oni Tiger); Titan Temple 7B (Gorilla King); Angels & Demons 20B, whose zone page shows separate Angel and Demon guardians (the Biomes table names ArchAngel, World Burner and Aetheron). Those figures are the wiki's Biomes page, read 21 October 2026.

Because each zone holds exactly eight pets on the normal route, the zone page doubles as a shopping list. The top egg in each zone is usually the one people fight over on a seven-player server; the second or third egg is often the better use of a run when the nest for the top one is camped.

A hatched pet's card shows two independent rolls: a colour mutation (the wiki also calls them auras) and a size in kilograms. Final income is base income multiplied by the mutation multiplier multiplied by the size multiplier — the wiki states the formula directly. The mutation table is short: Rainbow ×3.5 (roll weight 1 in 100), Parasite ×3 (only from the Parasite Egg in the feeding event), Fractured ×2.75 (from a Mutation Consumable, 10 % chance), Scrambled ×2.75 (from Dr. Scramble's Shop, 10 % chance), Golden ×2.5 (4 in 100), Spirit Bloom ×2.5 (Sakura Incubator), Bloom ×1.25 (Sakura event) and Silver ×1.2 (6 in 100).

Size is the quieter multiplier and, according to the wiki, the easier one to obtain. Each pet has a hidden base weight, and up to 125 times that weight the income scales by the weight ratio to the power of 37/60; beyond that, diminishing returns apply. The wiki's own worked examples: an egg at 100× base weight earns about 17× base value, at 200× about 23×, at 1,000× about 45×. Their combination examples are the ones to memorise — Golden plus Giant is ×7.5, Rainbow plus Huge is ×17.5.

Search 'steal an egg codes' and you will find a dozen pages listing codes. The community wiki's own Codes page, read on 13 September 2026, says the opposite in one sentence: there are no current codes in this game, and there is not even a way to redeem them. The official game description does not mention codes either. We keep a codes page anyway — because people search for it — but it explains what the real free-reward systems are (badges, the Rift's Boss Shop, event eggs) instead of inventing a list.

If a code system is ever added, that page will change on the day it is verified against the official game page or the wiki, and the date at the top of it will move.

The wiki's Gamepasses page (read 21 October 2026) lists two game passes with prices — X2 MONEY! at 399 Robux and X2 Growth Speed! (eggs grow twice as fast) at 467 Robux — and its Boosts page has a full table of temporary speed multipliers, from ×2 for 3 Robux up to ×4K for 1,375 Robux. Bear traps, by contrast, are free: you have an infinite supply, can place at most three, cannot place them in the safe zone, and anything that steps in one is held for seven seconds. The game passes page on this site walks through when the 2x Money pass pays for itself and why the speed boosts are usually the better first purchase.

Every pet page is generated from the wiki's infobox fields — name, egg, rarity, zone, income, reward, grow time — and from the zone table, with the arithmetic (mutation examples, rank within zone) done by us and labelled as ours. The wiki's text is licensed CC BY-SA 3.0; we reuse its data with attribution and the same licence, and we do not reuse its images.

We do not publish trade values, per-egg hatch chances or update schedules, because no source in our register publishes them. Where a page says the source does not document something, that is the whole answer. Corrections go to the address on the contact page and are fixed the same day.
