… and there is still some leftover dialogue about that in the game, as you can see with Beedle here.

The decision to turn crabs into proper cooking ingredients was thanks to a single playtester who luckily stumbled across this “issue” during a session and convinced the lead director to change the recipes.

Nate had made it out to the beach, where he found some crab and a campfire with a pot at sunset. Feeling very pleased with himself, he threw some crab in the pot with some spicy peppers, only to find out crab wasn’t used for food recipes—it was for elixirs! This happened to fit perfectly with my own personal description of crustaceans as being “the insects of the sea,” but as an east coaster who grew up on crab, Nate wasn’t having it. He contacted Fujibayashi-san that night and began passionately explaining to the development team how much people like to eat crab, begging him to add crab dishes to the menu.
