Ponyo

Ponyo is a curious and mischievous young goldfish who lives with her father Fujimoto, a wizard who uses his magic to create and maintain the world under the sea. One day, Ponyo is washed ashore by a storm and meets Sōsuke, a young boy who lives in a small fishing village. Sōsuke takes Ponyo home with him and names her "Ponyo" after the goldfish he had once kept as a pet. Ponyo quickly becomes attached to Sōsuke and his family, and she begins to transform into a human girl. Fujimoto, who fears that Ponyo will lose her magic and her ability to live under the sea, tries to take her back, but Sōsuke refuses to let her go. A battle ensues between Fujimoto and Sōsuke, and Ponyo is caught in the middle. In the end, Ponyo's love for Sōsuke wins out, and she chooses to remain human. Fujimoto reluctantly agrees to let her stay, and he uses his magic to create a new world for Ponyo and Sōsuke to live in. Ponyo and Sōsuke live happily ever after in their new world, and they often visit Fujimoto and the other sea creatures
