Cash is the currency for staffs, weights, Speed, Carry, extra pet slots, and Rebirth. Animals produce it when they are kept at your base. The official description says they also earn Cash offline, and that Roblox Plus players get +15% Cash. Community pages call that same 15% a Roblox Premium benefit. The experience text says Roblox Plus. Read your own balance if you are unsure the bonus is applied.
Make the lineup do the work
- Hatch or claim an animal.
- Open Pets, or the base management view, and set the stronger displayed earners into active slots.
- Note the Cash balance and the clock.
- Wait one clean interval without buying anything, changing pets, or leaving.
- Spend only after you can see the difference.
The starting base holds 10 animals in the September 29 rebirth guide. More slots are sold for Cash or Robux. A video of a paid session also buys a 2x Cash pass, VIP, and extra slots. Those passes are real shop categories in that footage. Their Robux prices are not copied here, because the video does not state every price. The one pack price spoken on camera is exclusive pack number one at 40 Robux.
Mutated animals are described as earning more than the normal form of the same animal. No stable multiplier is published. If you own two versions of one animal, compare those two. Do not apply one animal's rate to a different species with the same variant word.
Offline Cash
Offline earnings are an advertised feature, not an unlimited copy of your online rate. Before you log out, record the lineup, the balance, and the time. When you return, record the credited amount and how long you were gone. Use that credit for the next purchase. If a guide promises a duration cap or a full online rate while you are away, it is ahead of the public description.
The 15% Roblox Plus line is a bonus on Cash, not a separate currency. Stacking rules with Rebirth, a 2x pass, VIP, and potions are not published as one formula. Turn one of those on, repeat the same interval, and keep the result you measured.
Spending without stranding the next run
Keep enough Cash for the repair you actually need. A staff you cannot afford after a Rebirth is a worse position than a slower multiplier. The rebirth guide says a Rebirth spends Cash and leaves animals, upgrades, and store purchases in place. Check the confirmation panel anyway. A Saturday update can change the cost.
Rebirth costs are in Rebirth. The 15% line and slots are also on Cash.
