Build your collection through hatching
The listed route to pets is hatching eggs. Collect eggs from beneath rocks and use the hatch option available in your current session.
Use pets as part of progression
Pet earnings connect the collection loop to money and upgrades. Check the current game interface to see your own pets and available actions; exact effects are not listed publicly.
Compare only what the game shows
If the game displays pet income or rarity, use those in-game values for your current version. Keep notes if you are comparing pets, because updates can change values.
No tier list without data
The public Roblox description does not name pets, publish stats, or establish a strongest pet. This page does not make a ranked list or promise a specific hatch result.
