Hi,Im trying to get the name of a 1980's cartoon movie. I do not remember very much about it, but I will try to give the you information the best I can. It had something to do with travelling to the edge of the world. It may have had something to do with the sun as well.I don't think there were people in it, I think there were animals and maybe some kind of creatures in it. There was a horse or something like that with big sharp teeth that would chase the main characters and open its mouth really wide and roar,and it also may have breathed fire, but I'm not sure about that. It also might have been anime. I saw it when I was very young so I really don't remember much more than that. I hope you can help me. I really liked it, and want my children to see it. Thank you.

I may be way off, but try the last unicorn. They had to travel to the sea and there was a bull that would breath fire. Hope this helps.

Possibly "Unico" (1981)

This may be way way off but... The Secret of NIMH ?
