So once apon a time, some old loser had two weird babies. And then after seeing how ugly Bonkey Kong was, he threw him off a mountain which gave him dramatic brain damage or something making him some weird freak of nature. Then in the year 1984 Bob saggot found him laying in a trash can so he adopted him and and to this current day he's living in some street alley somewhere.
