Mayberry Melonpool is the television-addicted, somewhat clumsy, not-all-that-intelligent Captain of the "Steel Duck." Oh yeah, and he's obsessed with getting a date. In short, he doesn't have a lot going for him.
Ralph Zinobop is the inventor of the "Steel Duck." He is eager to enter the next phase of his plan: to make money off his inventions to regain his rightful place as ruler of the Planet Zinobop — a planet that he was exiled from by his paranoid father several years ago. His other hobbies include wild get-get-rich schemes and drinking copious amounts of coffee. He also has a terrible temper.
Sam T. Dogg is completely out of his element. He’s super intelligent, a highly-skilled pilot and has the most common sense of anyone aboard the "Steel Duck." Also, no one takes him seriously because he’s a dog.
Ralph suggested cutting back on coffee? Blasphemy!
Not to mention hypocrisy.
Ah, but the less coffee Mayberry drinks, the more there is for everyone else. Everyone else being pretty much exclusively Ralph.
