"I'm not built entirely like a human," he said, voice softer, being serious. "I don't get a sore back from lifting stuff wrong, 'cause I don't have vertebrae. I just fall over if it puts me off balance. I don't get tired and have to take a break, I just use up battery power moving too much, and then I gotta go take a nap with my charger again. I know how to fall down and stay safe, and all of that. I was programmed to know those things."

"I haven't needed any physical maintenance since I first came online. The only thing actually wrong with me like that when I came here was, I needed oil for my joints. And our friend Foulques had some, so now I don't squeak all the time!"

Considering all the evidence on his shell, he was probably discounting all the cosmetic damage he'd suffered....
