Mutations
A mutation is a variant a caught fish carries. The species stays the same, a Disco Cod is still a Cod, but the mutation changes how it looks and what it is worth.
Your chance of mutating a fish is the Shift stat on your rod, and it is also affected by weather.
How you get them
| Source | Mutations |
|---|---|
| Weather events | Most of them. Weather runs automatically |
| Random chance | Some, at very low odds: Rainbow works this way |
| Staff events | Voided, Disco, Ghost, Confetti: these cannot be obtained any other way |
| Beast encounters | Kraken and Megalodon only |
Kraken and Megalodon
These two are uncatchable without a beast encounter. No amount of Shift or luck will produce them: you have to be there when one happens. See Events.

Tracked in the Fish Dex
The Fish Dex records which mutations of which species you have caught, whether you have landed a Disco Cod specifically, not just a Cod.
That is what turns 30-odd species into a genuinely long chase. Every fish has 31 possible versions.
