Palworld Mutated Eggs — What Do They Hatch Into?
Nobody can give you a lookup table, because the mutation species table has never been datamined — it isn’t in the game files the way breed power and the combo table are. What we can do is log what players have actually hatched, with counts and sources, and test the theories against it. One of them holds up in 94.5% of the reports we have; several others fall apart. Both are below, along with the reports that disagree.
How complete is this? Not very — and that number matters more than the log does. We have observations for 38 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; u/Saikotsu also confirmed a Broncherry in the party made both duplicated mutation eggs hatch as alphas.
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.
A mutated egg hatches pre-condensed — but not always to the same rank.
Most reports say 2 stars (u/hiddencamela, u/Zxar99, u/flyrmyr). One first-hand report says 3: u/Saikotsu's duplicated pair were 'both pre condensed to level 3'. We previously listed 2 stars as settled — that was too strong.
The pattern the reports do show
Players on r/Palworld noticed something and put it into words: a mutation seems to land on a Pal ranked above the one the pair would normally make. That is a testable claim — breed power is the game’s own ranking number, and we have the combo table, so we can check it against every report in the log. Here is how it holds up.
94.5%
of reports fit
52 land on a stronger Pal than the expected child, 3 don't
None
legendaries or tower bosses
Across 51 reports and 33 distinct mutants, not one is a legendary or a tower boss
510
median mutant breed power
The median across all 299 Pals is 1660 — and lower means rarer, so mutants cluster hard at the strong end
What it doesn’t tell you
A direction is not a prediction. The theory says a mutant should be stronger than the expected child — it says nothing about which stronger Pal you get, and the log has a pair (Anubis × Anubis) that gave one player two different species. So this narrows the field; it doesn’t give you a lookup. Pairs whose normal child is already at the top of the ranking have nowhere to climb, and sure enough 4 reports in the log simply stayed put.
The 3 that break it
- Anubis + Jormuntide Ignis normally makes Eidrolon (300) but the mutant was Anubis (480) — weaker, not stronger. Reported by u/Eruionmel, seen 1.
- Jetragon + Ophydia normally makes Ophydia (230) but the mutant was Dualith Noct (250) — weaker, not stronger. Reported by u/CyberAceKina, seen 2.
- Jormuntide + Blazehowl normally makes Jormuntide Ignis (170) but the mutant was Wumpo Botan (610) — weaker, not stronger. Reported by u/Kind-Apricot6348, seen 1.
All of them are one-off sightings, which is also where a misremembered parent is most likely. We’re listing them rather than dropping them.
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 |

Questions the reports have now settled
These were open arguments a few days ago. Enough first-hand reports have landed since that we think they’re answered — with the dissenting reports kept in view rather than tidied away.
Does Grintale duplicate mutated eggs, and are the twins identical?
Yes it duplicates them, and no they are not identical. Both eggs hatch the same mutated species, but each rolls its own IVs and passives.
- u/Islalala9 (113 upvotes, first-hand): duplicated three mutation eggs; all three pairs hatched the same species with different rainbow passives.
- u/Sw33tR0llThief: 'I got a duped pair of incineram noct from a mutation egg and they each of 4 different passives.'
- u/Saikotsu: twin Gloopie Primo, one rolled Light Footed and the other Remarkable Craftsmanship.
- u/Gabe164 refines it: the two guaranteed rainbow passives get re-rolled, the two inherited from the parents stay the same.
- Requirements, from u/Islalala9's testing: Grintale's saddle must be crafted, it only needs to be in your party (not ridden), and it works on manual pickup from the breeding pen but not the Ancient Hatchery (u/turtles1236).
- Duplication chance scales with condensation: 50% at partner level 1, 55% at 2, 75% fully condensed (u/alice_op, u/KirroKit, u/Malkoy).
- Dissent worth noting: u/JoebiWanKenobii reports the twins as literal duplicates, and u/FrostFallen92 says the same for regular eggs.
Can a mutation produce a tower boss or a legendary?
Almost certainly not. They appear to be excluded from the mutation pool.
- u/Varue: 'No, you cant get them from mutations. they are excluded from that pool.'
- u/OpinionsGetYouBanned: 'Tower bosses can not be bred in 1.0.'
- u/maijqp: 'You can't get legendaries from mutations.'
- Our own log agrees: across every report we have, not one mutant is a legendary or a tower boss.
- Counter-claim on record: u/Vehemence1376 said mutation eggs can carry Legend and mentioned Aegidron with it — but that is the passive named Legend, not a legendary species, so it isn't the same claim.
Where the reports still 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
Same pair, same player, two different mutants
'The 2 mutations I had both happened when I was breeding Anubis x Anubis. The 1st was Celesdir noct the 2nd was Solenne.' Same breeding pen, same species pair, different results — the cleanest counter-example we have. — u/Primary_Foundation41
But there is a direction to it
Several players independently proposed that a mutation always lands on a Pal ranked above the child the pair would normally produce, capped below the legendaries. We tested that against the whole log — see the pattern section. — u/AetherBytes, u/Nifegun, u/maijqp
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
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
Do Broncherry and Broncherry Aqua stack to a guaranteed alpha?
Yes, additive — and the saddles are the catch
'The partner skills stack additively, but only apply if you build their saddles.' u/ted2167 first reported they don't stack, then retracted: 'I was wrong, turns out I just didn't have one of the saddles built.' u/Kinsume87: 'Ive hatched about 200 eggs now with them in party and every one has been an alpha.' — u/lillarty, u/ted2167, u/Kinsume87, u/KirroKit
Two separate rolls, not 100%
'It rolls 45% and then 55% and if one hits then you will get an alpha.' No saddle status given. — u/Round-Stuff-2557
Does Babysitter stack?
Split the question and it resolves
'Babysitter increases breeding speed by 30%, but it doesn't stack with additional Babysitters for breeding speed. However, the incubation speed does stack. I currently have 4 Babysitters in my base, and at the correct temperature even Very Small Eggs hatch in about 30 seconds.' Also: Braloha affects breeding speed, Dynamoff affects hatching — they are different stats people keep conflating. — u/Islalala9, u/Faeruhn, u/Hypragon
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.
