The Little Mermaid (Shrek)

The Little Mermaid is a character from Shrek 2. She is based on the the Little Mermaid from Hans Christian Andersen's fairy tale, and resembles Ariel from Disney's own version of the story.

Biography
The Little Mermaid was a fairy tale creature living in the seas of the kingdom of Far Far Away. She appears during Shrek and Fiona's honeymoon, when they are on the beach.

A wave comes in and washes up The Little Mermaid, leaving her on top of Shrek, kissing him. Soon after, Fiona throws her back into the sea, where it is implied that she is attacked by two sharks, though it is not certain whether she is eaten or merely attacked.

She is later briefly mentioned by Fiona's Fairy Godmother, who explains that her story has no ogres in it, although it may not be the same mermaid, since the character remains a mermaid and and seems to have loving feelings for someone other than her Prince.

Physical Appearance
The Little Mermaid has fair skin and a bright red hair. Unlike Disney's Ariel, her hair is short. Having the same color palette as the Disney character, the mermaid wears a pair of purple shells as a bra and its tail is green, with shimmering scales.

The mermaid on the cover of the The Little Mermaid book, from Fairy Godmother's library, also seems to have red hair and a green fish tail, implying that they are the same person.

Her appearance was a way of ridiculing Walt Disney Animation Studios.
