What change in preference did Ralph experience after moving to the seaside?

Ralph's preference for seafood changed positively after moving to the seaside due to the accessibility and freshness of seafood in that environment. Coastal locations often feature a variety of fresh fish and shellfish, which can be quite different from what is typically available inland. The exposure to local culinary traditions that emphasize seafood, along with the opportunity to try new and diverse dishes, likely contributed to Ralph developing a taste for seafood. This transformation in his eating habits reflects how local culture and environment can significantly influence personal preferences, especially in relation to food.
