Steal an Egg has 8 colour mutations in our list. A mutation multiplies a pet’s income. A pet’s weight is a separate roll and raises income too.
Whether a pet can carry more than one colour mutation, and how they combine, is not confirmed yet.
Not tested in game yet This is not confirmed yet. We will update it once we test it in the game.

Weight and size
Every pet hatches with a weight in kg, shown on its card. Bigger eggs hatch heavier pets. A heavier pet earns more than the same pet at its base weight.
Community reports say income grows with the weight ratio to the power 37/60. Above 125 times the base weight, it grows more slowly (power 2/5). This is not confirmed yet.
How mutations and weight stack
Income = base income × mutation multiplier × weight factor. Try it with your own pet in the calculator.
Conflicting values we’ve seen
Community lists do not agree on some multipliers, for example Silver and Rainbow. Some older lists also use fixed size tiers instead of weight. We show one value per mutation, mark it “Source: community wiki” until we test it, and update it after our own check.
