The story centers a young mermaid named Ariel, who is captivated by the world upon the surface. When she falls in love with a human prince, she makes a deal with a villainous sea witch to become human, herself, and earn his love before the agreed time runs out.

Lives in an underwater kingdom
In the sea
The princesses have to be 15 to see above
The sea
Little mermaid saw a shipwreck
Even saved the prince

Most of the time she visited him
Eventually, she goes to see the witch
Realised she wants to be human
Makes a deal with the witch
And loses her voice
Inland she marries the prince.
Deal gets broken by a kiss.
