Plot
Scrooge and his sisters go to Africa where Scrooge, for the only time in his life, acts like a scoundrel as he hires some criminals to attack a native village. In protest, Matilda and Hortense return to Duckburg while Scrooge goes around the world in search of more wealth. The whole time, he is followed by a zombie named Bombie. In the end he returns home as a hardened duck and as a result his family leaves him, but he finds comfort in now being the richest duck on earth. But this comfort is only temporary; the shame and remorse start to torment Scrooge, and his guilt and sadness grow up to the point where he loses his interest in money and retires.
