Mutation
Breeding has a low chance to produce a stronger Pal; mutated eggs hatch Pals with higher stats and a unique passive skill.
breeding tool
Breeding calculator
Covers 288 breedable Pals and recalculates results from the 1.0 formula pool and override table.
Which results are shown
After selecting a target child, all usable parent combinations are listed from formula reverse lookup plus overrides.
After selecting parents, the result shows child, rule type, derivation chain and 1.0 status.
Calculates one feasible path with the fewest breeding steps. Intermediate partners are assumed separately obtainable and no save data is read.
Official changelog
Breeding mechanics in 1.0
Four functional cakes
- Mushroom Cake：Slightly raises the chance of higher stats on newborn Pals.
- Vegetable Cake：Produces two Pal Eggs at once.
- Deluxe Vegetable Cake：Raises the chance of mutation and stat growth.
- Special Cake：Raises the chance to inherit multiple passive skills from the parents.
Skills and selective breeding
Inherited active skills are now randomly selected from the three active skill slots set on the parents.
Many new passive skills create new possibilities for selective breeding.
Cake supply line
Every pairing consumes cake (5 flour + 8 berries + 7 milk + 8 eggs + 2 honey). Verified 1.0 spawn spots for Mozzarina, Beegarde and Chikipi, plus how to stop base Pals from eating your eggs.
Calculation rules (reproducible)
| Rule type | Calculation |
|---|---|
| formula | child = the Pal in the formula pool whose CombiRank is closest to floor((rankA + rankB + 1) / 2); exact ties use the verified winner table. |
| special_override | 135 special override combinations are entered row by row and take priority over the formula. |
| gender_locked | The Wixen / Katress line can return different children by parent gender direction and cannot be treated as an unordered pair. |
| self_only | 26 Pals can only be obtained by same-species pairing (legendaries and some exceptions). |
| same_species | Same-species pairing always returns the same species. |
Why manual calculations may differ
When manual calculations and tool results differ, the cause is usually one of these: the formula is only the base rule, ties have a separate winner table, special combinations override the formula, gender direction is not interchangeable, or the data version is different. The derivation chain labels which rule was hit.
| Common difference | How the tool handles it | Player next step |
|---|---|---|
| Only using the CombiRank average | The general formula is only the base rule; overrides, gender direction and self-only breeding can change the result first. | Read the rule type beside the result, not only the child name. |
| Tie handling is missing | When two candidates are equally close to the target value, the verified tie-winner table decides the child. | If your manual value lands between two Pals, check whether the derivation chain shows tie handling. |
| Special overrides were missed | 135 override combinations are entered row by row and take priority over the formula; manual formula checks are expected to fail on these. | If the result rule type is special_override, formula verification does not apply. |
| Treating parents as an unordered pair | gender_locked samples preserve parent direction and do not automatically treat A+B and B+A as the same case. | Read the gender-direction FAQ |
| Different data version | This site recalculates on 1.0 release data; the table you have may come from an older version. | Read data sources |
| Mixing old tools or community sheets | Third-party tables, old wiki copy and player experience are research leads, not the site's data canon. | Read data sources |
