All Eggs in Steal An Egg — Spawns, Sizes and What to Steal

How do eggs work in Steal An Egg?

Every egg sits in a guarded nest in one of the game’s biomes. The loop is always the same: steal the egg from its guard, carry it back to your base, and hatch it into a pet that earns money every second. What you earn is decided by three independent rolls at hatch — the pet’s rarity, its weight in kilograms, and its mutation — but the single biggest lever you control is which egg you choose to steal.

When do eggs spawn and respawn?

Nest spawns refresh on a cycle of roughly five minutes, followed by a short closed period while the biome restocks. Two practical consequences:

• If your favourite biome is picked clean, rotate to another one rather than waiting around — early biomes fill back up fast because fewer players camp them.
• Arriving just after a refresh gives you first pick of the largest eggs before faster players sweep through.

Which egg should you steal?

The reliable rule: steal the biggest egg you can safely get home. Egg size feeds the weight roll of the pet that hatches, and weight in kilograms is the base of your income — a pet near one million kilograms can earn millions per second before any mutation multiplier. Two refinements:

• A huge pet with a weak mutation can out-earn a small one with a strong mutation, because the multipliers stack on top of the weight-based base income.
• Late biomes hold bigger eggs but mean longer carry routes and meaner guards — the speed guide tells you exactly how much Speed you need before a biome becomes profitable instead of a death march.

Mutation and size are previewable before the hatch finishes, so watch the hatching bar: if a rainbow or golden shell tint appears, you have a guaranteed mutation coming.

Egg value: the official numbers we can verify

The developer’s own artwork confirms the scale late-game eggs reach: the T-Rex Egg and the Yeti Egg are both shown producing $89,121Sp per second (Sp is the septillion-scale abbreviation Roblox games use). Those are end-game showcase eggs — early Forest and Lake eggs earn a rounding error by comparison, which is why climbing the biome ladder is the real progression.

The complete egg-by-biome list

A full table of every egg name per biome is still being verified against the live game — the game updates almost daily and the community wiki is incomplete. Community resources name early Forest animals (Frog, Duckling, Jerboa, Fennec, Bird, Catfish) and biome guardians like the Forest chicken, the Lake swan, desert T-Rexes, the Snow yeti and a sleeping cosmic dragon, but we will not publish a per-egg table until it survives a live check. When it is verified, it will be added here and to the biomes overview.

Stealing from other players’ nests

The official description lists it as a feature: 🥷 Steal eggs from other players. Eggs you have already hatched can also be taken, so base defence is part of late-game play. The beginner guide covers the first-hour habits that keep you from being the easiest target on the server — and remember the server cap is only seven players, so someone always notices an undefended base.
