Steal An Egg Pets: Rarity, Income and the Pet Index

What do pets do in Steal An Egg?

Pets are the earning side of the game’s central loop. The official Roblox description says eggs hatch into pets and that pets earn money. A September 1, 2026 gameplay recording shows pet labels with income per second and a separate panel for pets that are active or equipped.

The game also names rarity, size, and mutation as dimensions. This page explains those visible fields without turning one player’s recorded values into permanent stats.

How do you get pets?

Pets come from hatching eggs. Current gameplay shows an egg moving from the Eggs inventory to a hatch countdown and then to a pet result. The official description independently confirms the egg-to-pet relationship.

The egg guide explains that sequence and the fields visible before hatching. It does not publish fixed hatch odds or a complete outcome list.

Which pet fields are currently visible?

Field	What the field can tell you	Current boundary
Name	Identifies a discovered pet	Every entity needs its own current verification
Rarity	Shows the rarity label used in the recorded build	The complete rarity ladder is not established here
Income per second	Shows an in-game earning rate beside a pet	One recorded number is not a permanent base stat
Discovery state	Separates known entries from silhouettes or question marks	It reflects the recorded account and build
Egg family	Groups possible pet discoveries under an egg type	The visible group is not asserted as complete
Active or equipped state	Shows which pets currently contribute in the player panel	Universal slot limits and upgrade rules remain unverified
Size and mutation	Confirmed as dimensions in the official description	Effects, multipliers, and combinations remain unknown

A field is useful only within its source date. Fast-changing games can rebalance rates or add new entities without preserving old screenshots.

What does the Pet Index show?

The reviewed gameplay opens a Pet Index that groups possible discoveries under an egg family. Visible entries show labels, while unknown entries remain obscured. Later in the same recording, an active-pet panel shows equipped pets and their displayed income.

This helps explain the interface, but it does not prove a current total. Numbers visible in a creator’s account can reflect that account’s discoveries, capacity, or the specific September build. They are not universal caps.

How should you compare pets?

First decide what job the comparison should answer. For early progression, displayed income and how reliably you can obtain or keep a pet may matter. For collection, discovery state, rarity, size, or mutation may matter. A single “best” ranking hides those different goals.

A responsible comparison would need:

1. a complete dated roster;
2. the same field definitions for every pet;
3. current income observations from a controlled build;
4. availability and obtainability evidence;
5. size and mutation rules; and
6. a disclosed scoring method.

That dataset is not complete, so this page does not publish a tier list.

Why is pet income not a trading value?

Income is an in-game output shown beside a pet. Trading value describes what players exchange in a market. The current public evidence does not establish a repeatable two-sided exchange flow or a sample of completed trades.

Rarity, size, mutation, income, and popularity may influence what players prefer, but none becomes a market price on its own. The trade-status page explains the evidence required before numeric values can be published.

What remains unknown?

This launch hub does not claim a complete pet list, exact current totals, permanent income values, a full rarity order, mutation multipliers, size formulas, or current availability for named pets. It also does not reuse third-party screenshots because those frames are research evidence without publication rights.

Future pet detail pages need a source-dated fact record and an original or licensed asset before they can go live. Until then, start with the beginner guide and use the visible fields in your current game rather than an undated table.
