How breeding works

Put one male and one female pal in a breeding farm, add a cake, and an egg appears about every five minutes. Three things are decided when the egg is made: the child's species, its passive skills, and its hidden stat bonuses.

Which species hatches

1. Two parents of the same species always make that species.
2. Some pairs are special couples with a fixed child. Relaxaurus and Sparkit, for example, always make Relaxaurus Lux.
3. Every other pair averages the parents' hidden breeding power, and the species closest to that average hatches. That is why two very different parents can make something unexpected.

Passive skills

The child rolls its passives in two stages. First it inherits from the pool of passives its parents carry: a 40% chance to inherit one, 30% for two, 20% for three, and 10% for all four. Then luck can add random passives on top, again at 40/30/20/10 odds for how many.

The cleanest setup is parents that together carry exactly the four passives you want and nothing else: the child hatches with all four about 10% of the time, roughly one egg in ten.

Hidden stat bonuses

Each pal carries hidden bonuses from 0 to 100 for HP, attack, and defense. For each stat separately, the child has a 30% chance to copy the father, a 30% chance to copy the mother, and a 40% chance to roll a fresh random value. Bred pals always share one value between melee and ranged attack.

Gender

Most species hatch male or female at a coin flip, but a few lean heavily one way - Kingpaca, for example, is almost always male. Gender only matters for pairing parents up and for the few special couples that require a specific male and female.

Cakes are the real bottleneck

Every egg costs one cake, and one cake takes 5 flour, 8 red berries, 7 milk, 8 eggs, and 2 honey. Time at the farm is rarely the limit - keeping the cake shelf stocked is. The calculator counts cakes for every plan so you can prep ahead.

A worked example

Say you want an Anubis early. Penking and Bushi's breeding power averages out to exactly Anubis, so one breeding farm, one cake, and about five minutes gets you your first egg. If the parents together carry exactly the four passives you want, expect around ten eggs - ten cakes and under an hour - for a perfect one.

All numbers are averages over many eggs, so a single run can be luckier or unluckier. Estimates assume default world settings.
