Open the egg you can hatch more than once. A single roll on an egg that empties your Wins leaves you with no backup pet.
Prices that were published for early worlds
School eggs, on the red bleachers:
| Egg | Wins | Published pets |
|---|---|---|
| Earth | 5 | Cat 50%, Dog 25%, Chick 10%, Frog 1% |
| Icy | 25 | Squirrel 31%, Deer 30%, Fox 23%, Bear 12%, Slime 4% |
| Lava | 125 | Parrot 50%, Monkey 30%, Tiger 15%, Mammoth 5% |
| Blackhole | 700 | Grass Mage 50%, Water Mage 25%, Magic Mage 15%, Spooky 3% |
Earth's listed chances add to 86%, and Blackhole's add to 93%. Those tables are missing pets or rates. Do not invent the missing share.
Gym eggs sit on white platforms: Crystal 7.5k, Molton 22.5k, Solar 75k, Moon 225k, Ice 650k, and Burning 2M. One older price list spells Molton as Molten and prices the Beach Clam egg at 635 million. The Beach guide updated August 14, 2026 prices Clam at 625m. Use 625m unless the egg sign in your server says otherwise.
Beach, Nuclear Bunker, and Void prices continue upward: Coconut 5m through Poseidon 15b, Rust 75b through Nuclear 240qa, then Void 300sx, Wormhole 3sp, Nebula 10sp, and Star 100sp. Every pet from those eggs is on the pet pages.
How to choose
- Hatch until you have a pet equipped. Earth is enough for that.
- Move to the next egg when you can pay for several hatches, not one.
- If the top egg in the world would spend almost all of your Wins, stay on the previous egg and fight a faster boss.
- Check Free Gifts and the Season Pass for eggs. A starter guide also names Green Apple, Mushroom, and Godly Bone as snacks that give pets XP. Snack amounts were not published.
- Ignore 2023 "best pet" percentages. The official listing now says there are 2500+ pets, so an August 2023 ranking is not a current loadout.
Palm, Molton, Nuclear, Nebula, and Star are among the eggs whose published chances do not add to 100%. Treat those percents as labels on the pets that were named, not as a complete probability model. The hatch calculator on this site only answers "at least one success" for a percent you type in yourself.
