Palworld Mutated Eggs — What Do They Hatch Into?
The honest answer is that nobody knows yet, and anyone who tells you otherwise is guessing. The mutation species table has never been datamined — it isn’t in the game files the way breed power and the combo table are. So instead of inventing a chart, this page logs what players have actually hatched, with counts and sources, and says plainly where the reports disagree.
How complete is this? Not very — and that number matters more than the log does. We have observations for 37 parent pairs out of 44,851 possible ones. That is 0.08%. Most entries below have been seen exactly once. Treat this as a notebook, not a lookup table.
What every mutated egg has in common
These are the parts multiple independent players report the same way. They’re the closest thing to settled facts on this page.
A mutated egg always hatches an Alpha.
Reported consistently across every account we've seen; no counter-report.
A mutated egg always hatches at 2-star condensation.
u/flyrmyr (8 breeding farms) plus multiple independent reports.
A mutated egg always carries 2-4 rainbow passives.
u/flyrmyr; corroborated by u/Frequent_Detail8724, u/Tawny2021 (3/3 with 4 rainbows each), u/SimianRex (10/10 with 3 rainbows each).
IVs are very high and re-rolled, not inherited — reports cluster at 91-100 even from 100-IV parents.
u/flyrmyr: 'All IVs were re-rolled between 91-100, from pure 100 parents.'
The egg looks visibly different and grants an achievement.
u/GNIHTYUGNOSREP, u/Frequent_Detail8724, u/Imaginary-Analysis39.
The mutant can be a different species OR the same species as the parents.
Different: most reports. Same: u/SimianRex (Aegidron 10/10), u/SunflowerTheLone (Whalaska), u/Eruionmel (Anubis). Top-tier pairs seem to skew toward same-species.
The report log
Every row is something a player says they hatched. Where one pair has produced the same mutant several times, the count is in the third column — those are the rows worth trusting. Single sightings are just single sightings.
| Parents | Hatched | Times seen | Reported by |

Where the reports disagree
This is the useful part. Every one of these is currently being stated as fact somewhere by someone — and every one of them has a credible player report pointing the other way.
Is the mutant species predictable from the parents?
Looks near-deterministic per pair
Jormuntide Ignis x2 → Eidrolon Ignis reported 3/3, 2/2 and 6/6 by two independent players. Aegidron x2 → Aegidron 10/10. Dupin x2 → Whalaska Ignis 3/3. Hartalis → Aegidron 5/5. Mammorest x2 → Moldron 3/3. — u/mogin, u/Purple_Pack_5740, u/SimianRex, u/Tawny2021, u/zerol1ve
Same pair gives different species
Shadowbeak x2 produced four different mutants for one player. Eidrolon gave Ophydia and Knocklem Ignis. Jetragon + Ophydia gave Dualith Noct and Eidrolon Ignis. — u/LoboSandia, u/Reakaron, u/CyberAceKina
Refinement: parents' passives may be part of the input
'It's always the same Pal in the mutated egg, if you don't change the parents, including their passives.' Nobody has tested this. — u/Entgegnerz
What is the mutation rate?
~5-10% on normal cake
Estimated across 8 breeding farms. — u/flyrmyr
~1-2%
Counted: 3 in ~200 eggs, 2 in ~150, 2 in ~100. — u/mogin
1% base / 3% with Deluxe Vegetable Cake
Stated without a method. — a widely-shared PSA
Do the mutation-boosting cakes actually work?
No effect observed
'The mutation boosting cakes seem to have no effect for my save.' — u/flyrmyr
Raises the rate to ~3%
Stated without a method. — a widely-shared PSA
Does egg size determine the pool of possible mutants?
Yes
'The mutation egg size large/huge etc defines the pool of hatchable pals.' — u/flyrmyr
Counter-example from the same player
'Common egg parents (yakumo line) has dropped a few huge mutations though, so it doesn't always match the size the parents would usually produce.' — u/flyrmyr
Can a mutation produce a tower boss or legendary?
No — they're excluded
'Mutations are restricted not to ever make these unique pals.' — u/sansetsukon47
Yes
'Mutation eggs have a chance to have legend, gotten a few aedrigon with legend.' — u/Vehemence1376
Are Grintale's duplicated eggs still mutated?
Implied no
Wrote '(not counting grintale dupes)' when tallying mutations. — u/LoboSandia
Yes
Credited Grintale for getting 4 mutated eggs. — the GRINTALE thread OP
Do mutants actually have better stats?
It's the free condensation, not the stats
'Mutated pals CAN already have condensed LVs. THIS is the reason for better stats. BUT when max condensed both a normal and a mutated pal will have the exact same.' The follow-up question got no reply. — u/Chaz1890
Is the mutant drawn from the same tier as the parents?
Disproven
A pair of Woolipop — a starter-tier Pal — produced an Aegidron. One report kills both the 'same tier' theory and the 'average breed power' theory. — u/Suppytkyngyy, u/Intelligent_Money902
How to help
The only way this gets solved is more hatches. If you get a mutated egg, the useful details are: both parents (and their passives — one report suggests those matter), what hatched, how many mutated eggs you’ve had from that same pair, and which cake you used. The counts are what separate a pattern from a coincidence.
Reports here are collected from public r/Palworld threads and credited to whoever posted them. If yours is listed and you’d rather it weren’t, or we’ve got a detail wrong, say so and it comes off.
Why this page looks different
The rest of PalRoute is marked 1.0 Verified because the numbers are read straight out of the game files. This page can’t claim that, so it doesn’t. It’s a report log — the badge says so, the counts say so, and the disagreements are left in rather than tidied away. For the parts we can verify, see the breeding guide.
