Of all animation film I've watched in my entire life, this one is on top, even it's an old film though. I've never ever cried over animation but this one touched my heart a lot. Great plot twist, excellent storyline even great soundtracks! All are beautifully combined to create such a perfect quality movie with meaningful messages inside and not gonna lie is educational! Perfect for science learning for kids even the film will bring you to tears. Congratulations to the production team for making such an excellent animation. I'm so addicted with this film now. Thanks to that one review video too if I never noticed that vid I would never know such VALUABLE film is exist.
