FAQ

What are sizes and mutations in Steal Anime Eggs?

The official description says you can discover rarer eggs, anime, sizes, and mutations, but it does not define mechanics. A reviewed video showed kg labels on units (single source, 2026-09-27).

What rarities does Steal Anime Eggs have?

Roblox sells passes named Epic, Legendary, Mythic, and Secret (snapshot 2026-10-12). Lower tier names are not listed in official text; video audio mentioned uncommon/epic once without UI proof.

What is the Cosmic Egg?

One official Roblox thumbnail includes the text COSMIC EGG pointing at a large blue block-style egg. We can confirm the promotional label only—not in-game drop rates or spawn locations.

Are there published drop rates?

No. Roblox descriptions, badges, and APIs we use do not expose hatch odds. We do not invent percentages.

Rarity content online often describes BlinkWorks or Steal An Egg pets. Anchor to place 96727061242653 using which game before you grind for a named egg.

What do rarity, sizes and mutations mean here?

The Roblox description’s final step says: “Discover rarer eggs, anime, sizes, and mutations!” That is the full T1 official wording—no glossary, no odds. VERIFIED 2026-10-12

We expect (T3) sizes change how a unit looks or scales and mutations add variant rules, similar to other collection simulators, but the developer has not documented formulas. EXPECTED 2026-10-12

According to Superlex Plays (2026-09-27, single source), a placed unit showed a kg weight label (example 32.8 kg on screen). That supports a size dimension without proving mutation UI. REPORTED Superlex Plays · 2026-09-27

Rarity-tier game passes, Roblox game-passes API, snapshot 2026-10-12. The developer does not state what each pass does.

Official text does not state what each rarity pass does—Roblox lists no description text for any pass. Names imply access or luck tiers; that is T3 inference only. EXPECTED 2026-10-12

Video audio (single source, 2026-09-27) mentioned uncommon and epic hatch results without a clear UI screenshot tied to those words—we do not treat Uncommon as a verified tier name. REPORTED Superlex Plays · 2026-09-27

What is the COSMIC EGG?

One official Roblox promotional thumbnail prints the words “COSMIC EGG” beside a large blue block-style egg with glowing rings. VERIFIED 2026-10-12

We can say the marketing asset labels that egg “Cosmic Egg.” We cannot verify the same string appears in-game, its rarity tier, or how to obtain it. EXPECTED 2026-10-12

Official promotional thumbnail from the game’s Roblox page; characters belong to their respective owners.

What we do not publish (and why)

We omit tables you see on other wikis when they lack T1/T2 backing for this place ID:

Hatch percentages or mutation names
Complete egg or character indexes
Tier lists ranking specific collectibles
“Best egg” rankings

Publishing guesses would contradict our verification policy.

How to check an egg yourself

Open Index or Eggs tabs (seen in reviewed footage—T2).
Note Robux rarity pass names on the live Roblox page versus our price snapshot.
Train Speed if a zone gate blocks you—see Speed and treadmill.
Screenshot anything you think is new; we need first-party proof before we encode it as T1.
