Three mermaids deflect an asteroid by shooting it with water

When Sosuke, a young boy who lives on a clifftop overlooking the sea, rescues a stranded goldfish named Ponyo, he discovers more than he bargained for. Ponyo is a curious, energetic young creature who yearns to be human, but even as she causes chaos around the house, her father, a powerful sorcerer, schemes to return Ponyo to the sea.

A behind-the-scenes documentary directed by Kaku Arakawa, documenting Hayao Miyazaki's creative process in creating the character of Ponyo during the production of Ponyo on the Cliff by the Sea.
