Steal an Egg values: what actually makes a pet worth more (and why there is no value list here)

There are four things this page will not do. It will not publish a value list, because no source measures one. It will not describe how trading works, because nothing in the register documents a trading system. It will not rank pets by demand, because demand is not observable from outside the game. And it will not use the word 'community-tracked' as if it were a source.

What it will do is use the numbers that are published — base income, mutation multipliers, the size formula, grow time, zone gates, and which pets are obtainable at all — to explain worth in the only terms that can be checked.

Every pet has a listed base income, and it tracks rarity almost perfectly: Commons earn $1–6/s, Legendaries $1.8K–130K/s, Secrets $1.25M–215M/s, Eternals $65M–900M/s, Divines $1B–3.5B/s. Base income is the floor of a pet's worth because it is what the pet does every second regardless of anything else. Two pets of the same rarity can differ by a hundredfold, though: the Legendary Brr Brr Patapim earns $1.8K/s and the Legendary Crustacia $130K/s, so 'it is a Legendary' tells you far less than the number does.

The wiki's Mutations page gives seven multipliers: Rainbow ×3.5, Parasite ×3, Fractured ×2.75, Golden ×2.5, Spirit Bloom ×2.5, Bloom ×1.25, Silver ×1.2. Three are natural hatch rolls with published weights — Rainbow 1 in 100, Golden 4, Silver 6 — and four come only from events or consumables. A mutation multiplies base income, so its worth is proportional to the base it lands on: a Rainbow on a Chicken adds $2.50/s, a Rainbow on a Mutant Shark adds $537.5M/s.

Scarcity matters separately from the multiplier. Parasite (×3, only from the Parasite Egg in the feeding event) and Spirit Bloom (×2.5, Sakura Incubator) are event-gated; once their event ends, no new ones enter the game. That is a reason a Spirit Bloom pet might be worth more to a collector than a Golden of the same base, even though the multiplier is identical.

Size is the multiplier most players under-weigh. It is rolled independently of colour, shown as kilograms on the pet card, and the wiki says it has a major effect on final income because size rolls are easier to get than rare colours. Up to 125 times the pet's hidden base weight, income scales with the weight ratio to the power of 37/60; beyond that, diminishing returns. The wiki's own examples: 100× base weight ≈ 17× income, 200× ≈ 23×, 1,000× ≈ 45×. Its combination examples set Giant at ×3 and Huge at ×5.

So a Huge, un-mutated pet (×5) is worth more than a Golden, normal-size one (×2.5), and a Rainbow Huge (×17.5) is worth more than the next rarity tier's plain pet in most zones. When comparing two pets, look at the kilograms before the colour.

Grow time is a cost. A Nightflame is 16 hours of exposure to six other players; a Rhinotaur in the same zone is 29 minutes for $17.5M/s. An already-hatched pet has paid that cost; an egg has not. If anything in the game were tradeable, a hatched Eternal would be worth more than an Eternal egg for that reason alone, and the difference would be larger on busy servers.

Twenty-three pets are event-only and, per the Eggs page, never spawn in nests; when their event is over there is no new supply. Seventeen are Rift pets available only while the Rift event runs. The rest are zone pets that respawn on a five-minute cycle behind a speed gate. Whatever a pet's numbers, a pet nobody can obtain any more is worth more to the people who want it than one anyone can farm this afternoon — and a pet behind a 7B speed gate is worth more than its income implies simply because 0.8 % of players have reached the tier (Roblox badge statistics, 13 September 2026).

Multiply base income by the mutation multiplier by the size multiplier for each — the calculator page does it — and you have the income comparison. Then ask three yes-or-no questions: is it already hatched; is it still obtainable; is it behind a gate the other player cannot reach. Each yes is worth more than the number suggests. That is as far as sourced reasoning goes. Anything past it is opinion, and this site labels opinion as opinion.

Because none of them is measuring anything. A value list needs a market — a trading system with visible offers — and Steal an Egg does not document one. Lists that exist are copied from other games' formats and filled in by guesswork, which is why the same pet can be 'worth' three different amounts on three sites on the same day. When the sites disagree and the source is silent, the source is right.

Take two Lake Leviathans, base $220K/s. One rolled Golden at normal size: 220K × 2.5 × 1 = $550K/s. The other rolled no colour but Huge: 220K × 1 × 5 = $1.1M/s. The plain-looking one earns twice as much. Add a Golden roll to the Huge one and it is $2.75M/s — more than a normal Bronto, the Cosmic of a zone three gates away. If value meant anything tradeable, the kilograms on the card would matter more than the colour, and the colour more than the name.

Event pets never spawn in nests, so their supply is fixed once their event ends. By base income: Mecha Dreadscale $4B/s, Dreadscale $2B/s, Mecha Krakenoid $1B/s, Mecha Crocodon $680M/s, Ember Dragon $600M/s, Krakenoid $500M/s, Mecha Crawler $320M/s, Mecha Froggo $155M/s, Strawberry Elephant $110M/s, Drilla $100M/s, Mecha Scorpio $45M/s, Scorched Dragon $35M/s, Crocodon $30M/s, Shadow Dragon $25M/s, Bomboclat Crocolat $20M/s, Baby Aurora Dragon $5M/s, Crawler $1.5M/s, Mangolini Parrochini $800K/s, Froggo $50K/s, Belula Beluga $40K/s, Scorpio $10K/s, Bananita Dolphinita $400/s, Tung Tung Sahur $100/s. The wiki does not date the events; the updates page tracks what it does record.

Since income is the first factor, here is what each rarity label actually spans in the database, so 'it is a Mythic' can be translated into a number range.

Every number on this page is a fact about income, time or availability, and every one of them is checkable against the wiki and the Roblox page. None of them is a price. If the game adds trading and a market forms, prices will exist and will be observable in the game — and then this page will report what is observed, with the date, the same way it reports incomes now. Until then the honest answer to 'what is my pet worth' is the calculator's number, the pet's grow time, and whether anyone else can still get one.
