Sundiata, an epic of old Mali

The story takes place in Mali where a hunter defeats the red bull and marries one of the girls of the king, the problem is that the old woman who was the red bull ask the hunter to marry an specific girl from all of the daughters of the king, she has not beautiful at all, and the court didn't like her at all, and the problems got bigger when the first baby arrives, because he is already 7 years old and he doesn't walk yet. Other 2 children came and nobody knows what will happen, what would the king choose?
The first son, the one from the first wife or the next 3 with the ugly woman he married?

It was kind of confusing because of the names and stuff but I think it can have a good end, anyway is just the beginning.
