Every Steal An Egg mutation and its income multiplier.
Every pet rolls two separate things when it hatches: a colour mutation and a size. Both multiply its income, so a big pet with a rare colour can earn many times its base rate.

How size works
Size is rolled separately from colour and shows as the pet's weight in kg. That is why you can hatch a Golden Giant, or a plain Huge with no colour at all.
Income = base income x colour multiplier x size multiplier. Size rolls are much more common than rare colours, so weight usually matters more.
Growth slows down for very big pets: at 100x the normal weight a pet earns about 17x its base, at 200x about 23x, and at 1,000x about 45x.
| Normal pet | $100/s |
| Golden + Giant (x2.5 x 3) | $750/s |
| Rainbow + Huge (x3.5 x 5) | $1,750/s |
