Yeah there is a whole legend about them.

So the baobab was gods favorite but was also a bit needy. So they asked god for the thickest stem and god did give it to them. But they wanted even more and asked for the finest and nicest fruits, so god did also give them those. But the baobab, still wanting more, continued to ask for the most green and lush leaves. So god got a bit annoyed, ripped the tree out of the ground and planted it upside down again as punishment.
