The Little Mermaid (1968 film)

Its master, a young prince, is trying his best to keep the ship out of harm, but he fails, and eventually falls into the waves.

The three older mermaids, clad in blue, give their younger sister a red cloak, indirectly indicating the protagonist.

The hag offers her a potion that will turn her human, with the condition of having to lose her voice and bear a pain in her feet whilst walking.

He sees her beauty, and she dreams of a fantasy world riding with him on a winged horse into the stars.

The prince and princess, clad in wedding clothes, head back to the ship with the little mermaid holding the bride's train and an entourage following them.

They give her a magic shell, which will kill the prince and his new beloved, save her life, and return her to her mermaid shape.
