How to Breed Jellroy in Palworld 1.0
Jellroy is bred from Fuack Ignis × Rooby. Palworld 1.0 accepts 171 parent pairs in total, listed below, and every one of them produces the same child. The pair above is simply the one whose parents appear earliest in the Paldex.
From a starting Lamball, Jellroy is 1 generation away. On the default hatch setting (PalEggDefaultHatchingTime=1.0, one hour for a huge egg) that is about 1 hour of incubation, or about 3 days on a server set to 72 hours, the value older guides still quote as the default. Actual incubation varies with egg size and temperature.
Data: Palworld 1.0’s own breeding table. Verified against the 1.0 build; the 1.0 update reshuffled many Early Access combos, so older lists disagree on purpose.
Easiest parent pairs
Ordered by combined Paldex number, which is a rough proxy for how early each parent becomes available. Pairs that use a Jellroy as one of the parents are left out here, since they are no help in getting your first one.

Shortest breeding chain from Lamball
If you do not own either parent yet, this is the fewest generations from a Lamball to Jellroy. Keep the child at each step and pair it with the listed partner.

How long this takes on your server
Egg hatch time in Palworld is a server setting, PalEggDefaultHatchingTime, not a fixed game value. It is the single largest factor in how long Jellroy takes, and it is the reason two players report wildly different times for the same breed. Producing each egg takes about 5 minutes at a supplied breeding farm regardless of the setting.
| Hatch setting | Per egg | This breed (1 generation) |
|---|---|---|
1 (default) | 1 hour | about 1 hour |
72 (early-access launch default) | 3 days | 3 days |
0 (instant hatch) | instant | about 5 minutes, egg production only |
To change it, stop the server, then edit the value inside the single OptionSettings=(...) line of PalWorldSettings.ini. The server rewrites that file when it shuts down, so an edit made while it runs is lost. For example, half an hour for a huge egg:
On a Supercraft server this is a field in the panel rather than a file edit. What the four breeding-related settings do, and the ones that quietly limit how many breeding farms a base can run, are covered in the breeding settings reference. The full list of keys is in the Palworld configuration guide.
Plan the IVs before you commit
The pair decides which Pal you get; it does not decide the stats. If you are breeding Jellroy for passives or IVs, the breeding calculator shows every pair for Jellroy, and its planner converts parent IVs and your hatch-time setting into an expected egg count and a wall-clock estimate. If you already own some of the parents, list them in the calculator's find mode and it keeps only the pairs you can make now, or let the Pal Box inspector read them straight from your save.

Common questions
What is the easiest way to breed Jellroy?
Pair Fuack Ignis with Rooby. Of the 171 accepted pairs, that is the one whose parents sit earliest in the Paldex. Every other pair listed above produces the same child, so use whichever two parents you can actually get.
How many parent combinations produce Jellroy?
Palworld 1.0 accepts 171 parent pairs for Jellroy, of which 170 use two different species. Both orders of a pair count once.
How long does it take on a dedicated server?
Starting from a Lamball, Jellroy is 1 generation away. On the default hatch setting (PalEggDefaultHatchingTime=1.0), allow about 1 hour of incubation. On a server set to 72 hours, allow about 3 days. Actual times vary with egg size and temperature.

Breeding Jellroy on a schedule you control needs a server whose hatch time you can set. A managed Palworld server exposes that setting in the panel, keeps the world running while eggs incubate, and snapshots it before you change anything.
