Ariel made a cameo appearance in Shrek 2, when Shrek and Fiona are on their honeymoon.
Ariel kissed Shrek on his honeymoon on a beach when a wave washed him and Fiona up. Fiona saw this and got angry, so she dragged Ariel by the fin and threw her straight into the ocean. When she landed, two great white sharks devoured her.
She is then briefly mentioned by Fiona's Fairy Godmother, explaining that her story has no ogres in it.
- The appearance of the Little Mermaid in the film is similar to that of the Little Mermaid (also referred to as Ariel) in the Disney film and she is the only princess in the Shrek films that bears a notable amount of resemblance to her Disney counterpart.
- The character featured in the Shrek films bears resemblance to that of the Disney character, however appears to have a completely different personality. All of the other princesses in the Shrek films have made references to the Disney films they were featured in.
- The Little Mermaid is the only Disney Princess to appear in a single Shrek film (though others, such as Mulan and Pocahontas, have yet to appear in any).
