One great moral animated short story is 'The Boy Who Cried Wolf'. It teaches the importance of honesty. The boy lies so many times about the wolf coming that when the wolf actually arrives, no one believes him.
The animated short 'The Little Prince' also has many moral lessons. It shows how important it is to see the true essence of things and people, not just the surface. It also touches on themes like friendship and love. The Little Prince's adventures on different planets make us think about our own values.
