Net a Fish mutations and fusion: Shiny, Gold and Haunted

The fusion ladder

The creator explains fusion in the description of the Auto Fuse pass: “The cooler fuses fish by itself as soon as a stack has enough. It keeps going up the ladder (10 → Shiny, 8 Shiny → Gold, and so on)”

So fish in your cooler fuse once a stack is big enough, and each step up needs a stack of the step below.

That makes one Gold fish worth 80 of the base fish in fusion terms (8 × 10). The store text does not say how much more a Shiny or Gold fish earns in your pool.

Fusing by hand or automatically

Fusion happens in the cooler. Auto Fuse (199 Robux) makes the cooler fuse by itself as soon as a stack is big enough, and keep going up the ladder.

The shop also sells Instant Fuse (29 Robux). Its name suggests fusing normally takes some time, but we have not timed it.

Mutations are a chance roll

Mutation Hunter (249 Robux) gives a “2x mutation chance”, so mutations are random rather than fused. The base chance is not published.

The store text does not say whether Shiny and Gold count as mutations in the game’s own menus. Until we confirm it in-game, this page lists fusion steps and random mutations separately.

Haunted fish

The only mention of Haunted in the store is in the Boss Hunter pass: “Hollow King – 1.5x candy, 50% Haunted chance”. That links Haunted to the Hollow King boss, but not whether it is a mutation you can also get from normal casts.

Still to document

We will add these once we can record them in-game.

• The base mutation chance, and every mutation name.
• The fusion steps after Gold.
• How much more Shiny, Gold and mutated fish earn in your pool.
