An upgrade pays back within an hour once each new slot holds an animal earning at least the amount below. The area is the first one with an animal that earns that much.

| 1 | $40.0M | $5.56K/s | Desert | Snake ($7.50K/s) |

Mutations and sizes raise an animal's income, so a Gold or BIG animal gets you there sooner. Income for every animal is on all animals; the level for each area is on area unlock levels.
