Combining multiple mutations

Add only each mutation’s bonus above ×1. Golden + Rainbow gives ×5; multiplying ×2.5 by ×3.5 would give an incorrect result.

Mutation multiplier = 1 + sum of bonuses above 1

Pet size and income table

Compare a pet’s actual weight with its species reference weight. More weight increases income, but not proportionally. Mutations do not change this conversion.

Weight ÷ reference weightSize income multiplierExample: $100/s base income
×1×1$100/s
×2×1.53$153.33/s
×5×2.7$269.79/s

Hypothetical example without mutations or other bonuses. Table values are rounded. This does not assign one reference weight to every pet.

Use the pet’s weight and the reference for the same species. Do not mix species weights; the displayed weight may also be rounded.

How size is calculated

Up to 125 times the reference weight, the factor is (weight ÷ reference)^(37/60). Above that, growth slows down.

Scale = ∛(weight ÷ reference)

Scale ≤ 5: factor = Scale^1.85

Scale > 5: factor = 19.637875755794113 × (Scale ÷ 5)^1.2

Weight and mutation together

A pet with $100/s base income, 10 times its reference weight and Golden (×2.5) earns approximately $1,034/s. Calculate with the full factor before rounding.

Estimated income = base income × size factor × mutation factor
