Use the displayed game information
When an egg or pet is identified in your session, rely on the labels the experience provides. This is the best way to keep your choices tied to the current version.
Build a collection over time
The listed loop encourages collecting and hatching eggs to obtain pets. Keep exploring available rocks and use the progression options the game presents.
Treat rankings and odds as unknown
The public description includes no egg catalogue, pet stats, hatch odds, or rarest-item ranking. A specific name or percentage needs a current, verifiable source before it belongs in a guide.
Record version and evidence
If future official game updates publish rarity information, record the update and source so the information can be checked again after a change.
