Mutation rerolls let you roll a fish’s mutation at the Mutation Dealer, and fishing can award free Mutation Scrolls as rare chance drops.
Mutation rerolls are the Mutation Dealer’s service for rolling a fish’s mutation in Deep Fishing. Fish can also have a mutation when you catch them.
The dealer’s menu gives you mutation outcomes to compare, with separate regular and Ultra odds. This guide covers free scroll acquisition, dealer access, mutation probabilities, and paid spin bundles.

The dollar amounts accompany the 699 g Butterflyfish and 2.02 Kg Wet Carp in their respective menus. Keep those amounts tied to each fish: they appear beside mutation outcomes, while spin purchases have their own listed prices.
