According to series creator Tetsuya Nomura, the idea to put sea salt ice cream in the game came from when he was invited to the opening day of the theme park Tokyo DisneySea in 2001, where they sold this type of ice cream. He stated he liked the treat so much that his image of Disney strongly overlapped with it. He asked Disney if he could put the ice cream flavor into the game as a treat the kids in Twilight Town ate during summer vacation, but clarified that the game's writer Kazushige Nojima was responsible for incorporating this detail so heavily into the game.
