The 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. Due to his lack of knowledge of the human world, Scuttle gives this strange name to the object rather than the more-accurate "fork."
While exploring the sunken ship near the beginning of the film, Ariel encounters an item that has been noticeably spared the decay which has befallen every other object therein. The object is small and probably made of silver (or perhaps tin) due to its resistance to corrosion and the fact that stainless steel had not yet been invented. Attracted to this pretty and clearly-human tool, Ariel places the object in her bag and protects this bag even to the point of risking her life.
Scuttle, whom Ariel and Flounder consult after their discoveries, identifies this object as "the dinglehopper." According to him, it is used to comb the hair and thus achieve an aesthetically-pleasing appearance. Due to its shine, purity, and connection to the human world, Ariel displays the dinglehopper in a candelabra between a knife and a spoon in her undersea grotto. Once Ariel's grotto is uncovered by her father, however, it is presumably destroyed by King Triton, along with most of the other objects therein.
In Once Upon a Time, while attending Prince Eric's ball with Snow White, she sees a fork and Snow White quizzes her on what it is, with her calling it a mini-trident. Snow tells her it's a fork and when she sees Ariel pocket it, she tells her it's not very valuable.
Later, the Evil Queen reveals herself before them and orders Ariel to leave, stating that Snow White is going to die whether Ariel decides to go to Prince Eric or stays with her friend. Ariel begins to leave but then stabs the Queen in the neck with the same fork, distracting her while she takes the bracelet off Snow that turned her into a mermaid.
The dinglehopper also makes a cameo in Pocahontas. In the Descendants: Wicked World episode "Pair of Sneakers", Mal uses a fork, possibly the dinglehopper, to clear some cobwebs behind a shelf or a chest of draws.
In Ralph Breaks the Internet, when the Disney Princesses of Oh My Disney discovered Vanellope von Schweetz in their room, the Netizen version of Ariel used the dinglehopper as a weapon to use on their intruder. Just as she was about to use it, Vanellope reassured the princesses that she isn't a fret and is a princess herself.
- There is a slight animation goof on the Dinglehopper/Fork as it keeps alternating between having three or four tines.
