How stacked mutations pay
A pet can carry several mutations. The game adds up each one's multiplier minus one, so two mutations together are worth less than their product: a 1x Shark with Golden and Scrambled makes $63.8K/s, where multiplying would give $103K/s. Size multiplies on top; the earnings calculator takes any mix.
