The Little Mermaid year apart. When a mermaid turns fifteen, she is permitted to swim to the surface for the first time to glimpse the world above, and when the sisters become old enough, each of them visits the upper world one at a time every year.

When the Little Mermaid's turn comes, she rises up to the surface, watches a birthday celebration being held on a ship in honor of a handsome prince, and falls in love with him from a safe distance.
