Pets & eggs FAQ

What is the best pet in Build A Ring Farm?

The T-Rex (Secret, retired Dinosaur Egg) is the strongest reported pet with a 12x+ earnings boost and mutation upgrades. For cash players Hydra is a strong target: 0.5% from Epic, 15% from Legendary, or 52% from Secret Egg, with 8x earnings plus a 40% mutation-upgrade roll every 10 minutes. On a budget, Capybara's ~1.59x seed luck is the best value for seed hunting.

How do I get pets in Build A Ring Farm?

Buy cash eggs from the Egg Merchant at the far end of the map, then hatch them from your inventory. The merchant's stock rerolls every 5 minutes. Epic costs $10T, Legendary $100T, and Secret $7.5qd; limited event eggs are now retired.

How rare is the Hydra?

Hydra appears in three cash pools: 0.5% from the $10T Epic Egg, 15% from the $100T Legendary Egg, and 52% from the $7.5qd Secret Egg. At the Epic rate the statistical expectation is 200 eggs, or $2qd, but luck varies.

Why are my pets not working?

Pets only run their passive while deployed on the farm, not in inventory. Chance-based passives (Hydra/Mammoth mutation upgrades, Lion fertilizer) cycle every 5–10 minutes, so short sessions can look like nothing happens. After an update, rejoining the server re-registers your pets if an ability bugs out. Also check whether the pet needs Pet Treats to level.

Are there any egg codes?

No current code grants an egg directly. The UPDATE5 code gives a Super Pet Treat for levelling a pet you already own. Eggs are bought with cash from the Egg Merchant, or with Robux for limited eggs like the Dinosaur Egg.

How do I get the Fire Loong?

Fire Loong (Divine, 6.8x) is not in any egg. It comes only from the Update 7 Dragon Bundle (1,199 Robux, available until July 5, 2026), which also includes the Dragonfire Blossom seed and the Dragon Temple base skin. It is giftable, so a friend can buy it for you.

How do I get the Twilight Drake?

Twilight Drake (Secret, 5.8x) comes only from the Update 7 Twilight Bundle (799 Robux), which also bundles the Moonveil Lotus seed and the Twilight Garden base skin. It is not hatchable and is giftable.

Is the Dragon Bundle worth it?

For active players who run Super or Prismatic Fertilizer, the Dragon Bundle is one of the strongest paid pets — Fire Loong doubles a random active fertilizer every ~240s and you also get the $240K Dragonfire Blossom seed. But it's 1,199 Robux, leaves the shop July 5, 2026, and adds little if you mostly run pure cash setups.
