Sounds about right for Ponyo. Lilo and Stitch has a little more action, but if she's good with Moana it's probably fine. I have checked with my recently-minted five-year-old, who has seen all three movies in question, and she thinks they both sound a little too scary for a three-and-three-quarters-year-old to watch all of, and Moana is _definitely_ too scary. So there you are, a range of informed opinions. :)
