This video is exactly the kind of thing I would have loved in High/Middle School. It's a simple fable with cute animation and some truly bizarre and imaginative character design.
It also reminds me a bit of the film "Everybody Rides the Carousel," which I saw in High School psychology class. That film was also animated and explained the eight ages of human life and used different animals to symbolize fear, independence, love, etc. I admit part of the reason I liked it was the simplistic symbolism made me feel smart. But I asked my teacher for a copy of the tape after class and I still have it.
This is a lot less subtle, and I doubt it's meant for children, although children were treated with a lot more respect and less coddling back then, so who knows? Plus, it's blatantly anti-war, and I can't imagine that would be promoted in schools.

A GLORIOUS DAWN

This is beautiful and wonderful.
