Well, I can't make one for you, but I can give you some facts about Africa that you can put in your jingle. Africa is the second largest continent in the world, next to Asia. Africa is also where the world's biggest desert is: the Sahara. It was where the first actual human beings appeared. The climate in Africa is mostly hot and dry, but in the ancient times, it was much cooler. The people of ancient Africa were one of the first to adopt agriculture.
I hope I helped. :)
