Steal An Egg Special Eggs: Every Limited Egg Compared

Steal An Egg has two kinds of egg. Biome eggs sit in guarded nests and come back every 5 minutes. Special eggs never appear in a nest: you buy them, trade pets for them, or earn them from an event, and most of them have a reroll that turns a normal pet into a far better one.

There are 12 special eggs, and they are not close in value. The best one can produce a $9B/s pet; the worst caps out at $110M/s, which is less than a single Skeletal reroll’s floor. This page puts them side by side with the number that matters: the highest-income pet inside.

All incomes are base $/s, before mutations and size.

Every special egg, ranked by its best pet

The gap between row 1 and row 11 is 80x. That is the whole story of special eggs: chase the rerolls, ignore the rest unless you want the pets.

Luminous Egg: a 1% reroll on every hatch

The Luminous Egg arrived in Update 4 and replaced the Monster Egg. It works the same way the Monster Egg did: each hatch has a small chance to upgrade the pet you rolled into a special variant. The wiki gives the number: 1% per hatch, with 6 base pets and 6 matching Luminous forms in the pool.

There is no separate Luminous Cthulhu slot. You have to roll a Cthulhu and hit the 1% on the same hatch.

The interesting part is the bottom of that table. The Cthulhu reroll only doubles the pet, but the Spike reroll multiplies it by more than 23,000. Any Luminous hit is a huge upgrade, which is why the community treats Luminous pets as a separate species rather than a mutation. There is no documented pity system.

Extinction Egg: the highest ceiling in the game

Update 6 added the Extinction Egg as a paid egg with 6 extinct animals. Like the Luminous Egg it has a reroll, this time into a Skeletal version. The notes say “small chance” without a number and the wiki does not list one.

The floor matters more than the ceiling. The weakest Skeletal form, Skeletal Glyptodon at $550M/s, out-earns every biome Secret pet in the game (the best of those, Centaur and RazorFang, make $350M/s). If you are going to spend Robux on one egg, this is the one with the least downside.

Monster Egg and the Mecha reroll

The Monster Egg came out in Update 2 in the Robux Store with 6 monsters, each with a rare Mecha variant. Update 4 replaced it with the Luminous Egg, so the egg itself is retired; the Mecha forms still exist and still show up in trade.

The Mecha reroll chance is not documented anywhere. Note that a plain Dreadscale at $2B/s already beats every Mecha form except Mecha Dreadscale, so if you are chasing one specific result, this is the least efficient reroll family.

Laboratory eggs: Biohazard, Experimental, Unstable

Update 6 replaced the old Rift trade-in with Dr. Scramble’s Laboratory, where you hand in eggs rather than pets. A banner rotates between three pools, and each pool only accepts eggs from certain biomes.

Since Update 6, hitting pity guarantees the top reward of the pool instead of a random top-three, and pity carries over when you leave the server or the banner rotates. The number of trades needed is not published.

The cheapest acceptable eggs start in Prehistoric (18M Speed), so this is a mid-game system. The Unstable banner is the best of the three because Octophant at $4B/s is double the other two pools’ best.

Rift eggs: 3 pets in, 1 egg out

A permanent Rift in the lobby asks for 3 random pets and returns 1 exclusive Rift Egg. The pets it asks for depend on the active banner, and banners rotate roughly every 3 hours, synced across every server.

Riftborn is the banner you can feed earliest; its easy list is Jungle-to-Abyss pets. If you are mid-game, feeding the Rift is a reasonable way to convert junk pets into something above your current tier. Just do not confuse it with the timed Rift that opens on the map every 30 minutes, which pays Boss Tokens instead.

The eggs that are not worth chasing

• Brainrot Egg. Its six pets run from Tung Tung Sahur at $100/s (15s hatch) to Strawberry Elephant at $110M/s (4 hours). The top pet is worth less than any Skeletal form’s floor, and less than a plain Centaur. It is a fun early egg, not a late-game target.
• Dragon Egg. Three dragons at $5M, $25M and $600M, and no documented way to get the egg. Guides disagree on the source, so treat any “how to get the Dragon Egg” method as unverified.
• Monster Egg. Retired. Only the Mecha forms survive.

How to decide

1. Under 700M Speed? None of this matters yet. Farm biome eggs and push biomes.
2. Have Robux? The Extinction Egg has the best floor: even its worst Skeletal roll beats every biome Secret pet.
3. Free to play, mid-game? Feed the Rift Sacrifice and the Unstable DNA banner. Both convert pets or eggs you already have into $1B+ pets.
4. End game? Only the Luminous 1% and Skeletal rerolls move your income meaningfully, and both are luck-gated.
