Found the following article online, use it to answer the question: What is the name of the person whose inventions always fail?  Set in the Stone Age, Ishbo is the younger son of Mookoo, the leader of a tribe of cavemen. Ishbo is smarter than most of his tribesmen, but awkward and nerdy, living in the shadow of his much more physically impressive brother Thudnik. He hopes to use his superior intellect to become an inventor and raise his tribe above simple sticks and stones, but due to a combination of the flimsy materials available to him and the lack of support from his tribe they always fail. Ishbo also has had a lifelong crush on his childhood friend, Fardart. Much to his dismay, immediately after he finally expresses his love to her she is "clubbed" by Thudnik (and all that follows in the tradition of caveman stereotypes), and eventually married to him. Ishbo himself has never clubbed a woman, having his heart set on Fardart his whole life. After Fardart is betrothed to Thudnik, Ishbo begins to believe that he will never club a woman. He at first is too attached to her to consider clubbing another woman, and is further discouraged after a particularly ill-fated attempt at clubbing. Ishbo becomes quite depressed, a feeling which is escalated by his failure to prove useful on a mammoth hunt. He falls into a large pile of mammoth dung, then is eaten by the mammoth, and eventually excreted (or extracted – the scene itself appears as a series of animated cave drawings) from the mammoth when it is finally killed by the rest of the tribesmen.
