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

SourceMutations
Weather eventsMost of them. Weather runs automatically
Random chanceSome, at very low odds: Rainbow works this way
Staff eventsVoided, Disco, Ghost, Confetti: these cannot be obtained any other way
Beast encountersKraken 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.

Base is the default no-mutation state.

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.

Awaiting data

  • Which weather causes which mutation
  • Sell multiplier per mutation
  • Whether a fish can carry more than one
