Backflip for Animals! How to Hatch Eggs Into Pets

Quick answer

Hatching is what turns an egg you already have into a pet. The game's loop is: steal an egg from a guardian, bring it back to your base, and hatch it there to collect rare pets — some of which are mutated.

• Where: your own base — eggs are carried back there before hatching.
• Outcome: rare pets, and some are mutated.
• Afterward: the pet grows, earns money, and strengthens your collection.

Where you hatch: bring the egg back to your base

The game's description is where hatching gets a location. Its loop reads, in order: "Bring the eggs back to your base," then "Hatch and grow powerful animals," then "Build your collection and become stronger." Sequenced as written, an egg has to be carried home before it hatches, and hatching is described as growing the animal into a powerful collection member rather than as an instant conversion.

Two things the game's own text leaves open: the exact interaction and the timing. The How to Play doesn't spell out a button, prompt, or how long a hatch takes, so check what your base offers when you arrive carrying an egg and go from there. One wording note: the description text varies by version — older wording references "stages" where the current text says "biomes" — so treat whatever labels you see in-game as the ones that count.

What an egg hatches into

The current How to Play line is the full documented scope: "Hatch eggs to collect rare pets, some are mutated." Eggs produce pets, those pets are described as rare, and some come out mutated. That is where the text stops — it doesn't name which pets can hatch, list rarity percentages, give mutation rates, or break outcomes down by egg tier, and it never guarantees that a specific egg produces a specific rare or mutated result. Plan for variety in what you get, not a fixed outcome.

After hatching: grow, earn, upgrade

Both versions of the game's text tie the hatch directly to progression. The How to Play follows the hatch line with "Earn money from your OP pets," and the description reads "Hatch and grow powerful animals" ahead of "Build your collection and become stronger." The pet you hatch is kept: it grows, generates money, and makes your account stronger. No income values or growth rates are spelled out.

The practical next step once a pet is hatched: put its earnings back into the loop — "Train on the treadmill to gain Speed" and "Upgrade your treadmill and base" — so your collection keeps compounding and you can push further for the rarer eggs ahead.
