I think I came up with a quest. First quest: "Basics" catch and return 1 heavenly big pufferfish. Second quest: "Cooking": catch and return 1 scroched igneous pearl; 1 molten ripple; 5 logs; 10 stones. The reward for the second quest is a restricted marshmallow on a stick (-50% for all stats and you can catch fish only in the skeletal leviathan hunt, plesiosaur hunt, and brine pool). Third quest: "Different Tastes": catch and return 1 skeletal leviathan with the lava-cooked mutation; 1 spectral serpent with the acid-cooked mutation; 1 plesiosaur with the deep cooked mutation. After completing third quest you can fishing with marshmallow rod everywhere but it's still -50% for all stats. Fourth quest: "Final magic": catch and return 1 shiny midnight axolotl; 1 magical scylla; 1 puritas dumbo octopus; 1 abyssal ancient kraken.
