Compare the pet before judging its appearance
Steal Animal Egg sizes and mutations are features named in the official game description. They give you a reason to inspect new eggs and pets, but they do not supply a verified rarity ladder, mutation list or income formula.
Start with the information attached to the pet in your session. Its appearance can help you notice something new; its displayed values and selection behavior help you decide what to use.
In the gameplay demonstration, the player wonders why the best-selection option leaves out a larger-looking pet. Check the selection as well as the model’s size when comparing a new pet.
Keep three questions separate
When you get a new result, distinguish what it looks like, what the interface calls it and what it contributes.
| Question | What to inspect |
|---|---|
| Does it look different? | Visible size and effects |
| Does the game identify a special property? | The pet’s actual labels |
| Is it useful in the lineup? | Available values and selection result |
A visual glow is not enough to assign a named mutation. A large model is not enough to assign a multiplier. Use the label the game actually provides before repeating a claim.
If you are still working through placement and opening, see the hatching guide. Comparing results comes after obtaining them.
Review best selection after a new hatch
Check the active lineup when you add a pet. If the best-selection option is available, use it and inspect which pets are selected afterward.
Do not assume a surprising selection proves a bug. The complete selection formula is not established, so compare any visible values before overriding it based on appearance.
The Equip Best guide covers this review. It also explains why an unselected pet is not automatically a pet you should sell.
Do not chase an invented odds table
The sources used for this guide do not provide a verified complete mutation list or probability table. Check the current game for those details before pursuing a result based on assumed odds.
If an in-game display gives a percentage, read what that percentage applies to. A displayed chance for one interaction does not automatically describe every egg, every size or every event.
A pass or bundle name does not establish that it improves mutation odds. x2 Growth advertises faster planted-egg growth, not a guaranteed special result. x2 Cash advertises pet money, not a change to the hatch pool.
Decide what to keep with the actual trade-off visible
Before selling an unusual-looking pet, inspect its role and offered sale value. You may want to keep something for its appearance even if the current best-selection routine leaves it out.
If capacity is the problem, compare the expansion option with the pets you would remove. Check the current cost and lineup before deciding; there is no verified rule that all small pets are disposable.
The selling guide provides a pre-sale checklist. Review it before confirming a transaction you expect to undo later.
FAQ
Are different sizes and mutations official features?
Yes. Both are named in the official description of Steal Animal Egg. Their complete lists and formulas are not provided there.
Does a larger pet always make more money?
That universal rule is not established. The demonstration includes a larger-looking pet not chosen by the best-selection option; compare the actual displayed values.
What is the rarest mutation?
A verified complete mutation ranking is not available. Do not use a list from another game with a similar title.
Does x2 Growth increase mutation chances?
Its advertised benefit is faster growth for planted eggs. A mutation-chance increase is not included in the verified description.
Should I sell a special-looking pet if it is not selected?
Check its current values, your available space and whether you want to keep it. Automatic selection does not decide every collection preference.
