Every egg and its pet pool

Each row shows the exact chance within that egg; every published pool totals 100%. A dash means the full pet profile is not yet verified, not that the pet has no rarity or boost.

How to get eggs and hatch pets

Eggs are a pure cash (or Robux) sink once you find the merchant โ€” the hard part is affording the high-tier eggs.

  1. 1

    Find the Egg Merchant

    Walk to the far end of the map where the Egg Merchant stands. The shop stock rerolls roughly every 5 minutes, so the egg you want may not always be on offer.

  2. 2

    Buy the best egg you can afford

    Common Egg ($25M) and Rare Egg ($25B) cover early progression. Epic costs $10T, Legendary $100T, and Secret $7.5qd; compare the exact pool odds before spending.

  3. 3

    Unlock more egg slots

    Extra hatch slots let you incubate several eggs at once. Spend cash on slot unlocks before mass-buying Epic Eggs so you are not bottlenecked on one egg at a time.

  4. 4

    Hatch, then deploy and upgrade

    Equip your best pet to a farm floor, then feed Pet Treats and Super Pet Treats (from the Composter) to push its boost higher โ€” a fed Capybara reaches ~2.07x seed luck.

Build A Ring Farm eggs FAQ

How do you get eggs in Build A Ring Farm?

Buy cash eggs from the Egg Merchant at the far end of the map. Common costs $25M, Rare $25B, Epic $10T, Legendary $100T, and Secret $7.5qd. Dinosaur, Carnival, Beekeeper, and Wizard were limited Robux eggs and are retired.

What is the rarest pet from the Epic Egg?

Hydra is the rarest Epic Egg pull at 0.5%, a statistical expectation of 200 eggs or $2qd. Mammoth is next at 2.5%, followed by Polar Bear at 15%.

How much does the Epic Egg cost?

$10 trillion cash. It contains five pets: Crocodile 52%, Lion 30%, Polar Bear 15%, Mammoth 2.5%, and Hydra 0.5%.

What is the best pet to hatch?

For free-to-play, the Polar Bear (Rare Egg) is the strongest growth pet, and the Capybara (Common Egg) is the must-have seed-luck pet. Endgame, the Hydra (Epic Egg) and limited T-Rex (Dinosaur Egg) lead with 8x and 12x+ boosts.

How do I get the Hydra in Build A Ring Farm?

Hydra hatches from Epic Egg ($10T) at 0.5%, Legendary Egg ($100T) at 15%, and Secret Egg ($7.5qd) at 52%. Epic is cheaper per attempt but averages 200 eggs ($2qd); compare that with your access to higher cash eggs.

How do I get the Mammoth in Build A Ring Farm?

Mammoth appears in the Epic Egg ($10T) at 2.5% and the Legendary Egg ($100T) at 30%. There is no current code or documented non-egg source.

Can you get pets without eggs?

Yes. The Kitsune comes from the limited 799-Robux Kitsune Pack, the Starfall Griffin is a limited Divine pet, and Update 7's Fire Loong (Dragon Bundle) and Twilight Drake (Twilight Bundle) are Robux-bundle pets โ€” none of these hatch from an egg.

How do I get more egg slots?

Egg slots unlock with cash through farm progression. More slots let you hatch several eggs at once, which matters a lot when grinding low-odds Epic Egg pets.
