i would give everything to see a scene between ariel and eric where he finds out about all the different words she has for things (e.g. dinglehopper), and he tells her the real words for them. whenever ariel finds something new, eric becomes her new scuttle and she runs to him to ask him as many questions as possible. however, i do think eric is the kind of person to pick up on the names ariel has for certain things, loving the fact that they came from her interest in the human world, which eventually led her to him.
