Pets sit on your farm and quietly make it richer. Each one multiplies the income on its floor and runs a little ability on a timer, from dropping fertilizer to fully growing a plant or upgrading a mutation. Here you can line them up by rarity and see what each pet boosts, what its ability does, and where it comes from.
How to use this collection
Each card shows a pet's rarity, its starting earnings boost, the egg or bundle it comes from, and what its ability does. The boost is the Level 1 value and climbs with pet size and level. Pets are grouped by rarity, from Common up to Exotic.

How a pet pays you back
Every pet does two jobs at once. It multiplies the cash earned on the floor it stands on, and it fires an ability on a timer. The earnings boost listed for each pet is its starting value. The same pet pays more as it grows in size, from Regular up to Big and Giant, and as you level it up with Cash, so treat the number as a floor, not a ceiling. A common pet gives a small nudge; an Exotic one can multiply a floor's income many times over.
Picking the right ability
The boost tells you how much, the ability tells you how. Some pets just hand you a flat multiplier or a luck bump. Others grow plants instantly, drop stronger fertilizers, upgrade mutations, or buff your other pets. If you farm mutations, lean toward pets that upgrade them. If you want faster harvests, the instant-grow pets do more work. A weaker boost with the right ability can beat a bigger number that does nothing for your setup.
FAQ
What do pets actually do in Build A Ring Farm?
Each pet multiplies the cash earned on the floor it sits on and runs an ability on a timer. Abilities range from dropping fertilizer and fully growing plants to upgrading mutations, buffing your other pets, or skipping time.
Does a higher rarity always mean a better pet?
Higher rarity usually means a bigger earnings boost, but the ability matters just as much. A pet with a smaller boost but the right ability for your farm, like mutation upgrades or instant growth, can be the better pick for your setup.
Why is the earnings boost shown as one number?
The boost listed is the Level 1 starting value. The same pet earns more as it grows from Regular to Big to Giant size and as you level it up with Cash, so think of it as the floor rather than a fixed figure.
How do you get pets?
Most pets hatch from eggs you buy with in-game Cash, like the Rare, Epic, and Legendary eggs. Others come from special eggs, packs, or Robux bundles. The source for each pet is listed on its card.
What is the rarest pet?
The Exotic pets are the rarest tier, and they carry the highest earnings boosts. Pets in the Secret, Prismatic, and Divine tiers are also very strong and often tied to limited eggs or bundles.
