Skippy: The most gullible sentient being in the galaxy.
Contrary to popular belief, Skippy isn't actually stupid. He just believes every single thing he hears. Maybe it's stupid of him to be so trusting, but aside from that he's not an idiot. Interestingly, he would in a sense be the perfect soldier, because he would take absolutely any order without even the slightest hesitation. Who knows? Maybe he was originally destined for trench warfare, which would explain why he can't stop digging?
I don't know. Aside from his gullibility, Skippy is a pretty upbeat guy. He rolls with the punches, of which there are many, and never gives up his quest for Steph. He's just that innocent.
More info to come- maybe.
