Bumba was born when the world began. He got sick of looking at plants all the time so he vomited up nine creatures which became the ancestors of birds, reptiles, mammals and fish. He wasn't satisfied with that lot so he barfed again and chucked up a two legged being (Humans) which he thought was alright. He made a bunch more and made some strict rules for them to follow. This went well cept for one unruly wench called Tsetse Bumba who kept on wrecking shit up so Bumba turned her into lightening. Everytime you see lightening that's Tsetse Bumba going bunta.
