Flatworm Jim was the original pilot of the "Steel Duck." A six-foot-tall intelligent flatworm, Jim’s usefulness was cut short when he was injured, resulting in three versions -- good, bad and a two-headed neutral version. All three (or four) now live on Ralph’s asteroid tending to over 6 million hamsters.
Fred the Monkey was Ralph‘s last foray into augmenting lab animals for other purposes. Fred accidentally jettisoned himself in an emergency escape pod, sending him back to Ralph’s asteroid, where he and the rest of the original crew were created.
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.
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.
Sammy the Hammy is a genetic experiment gone horribly awry. Sammy is part of the ship’s equipment (he’s the engine) as well as a member of the crew. For this reason, Ralph never bothered giving him a name and he remained known as “Hamster 42” for much of his life.
The Picard Way…still cracking up on that 😀
