What does Ariel think a fork is for in Little Mermaid?

Dinglehopper (a.k.a. the fork) is an artifact from the sunken ship which Ariel and Flounder explore early in The Little Mermaid. It is in fact a fairly ordinary object, but Ariel prizes the dinglehopper, as it is an artifact of the human world for brushing hair. Due to his lack of knowledge of the human world, Scuttle gives this strange name to the object rather than the more-accurate "fork". According to him, it is used to comb the hair and thus achieve an aesthetically-pleasing appearance.
