With little shudders of disgust they all followed Zaphod down the incline into the crater, trying very hard not to look at its unfortunate creator.
"Life," said Marvin dolefully, "loathe it or ignore it, you can't like it."
The ground had caved in where the whale had hit it revealing a network of galleries and passages, now largely obstructed by collapsed rubble and entrails. Zaphod had made a start clearing a way into one of them, but Marvin was able to do it rather faster. Dank air wafted out of its dark recesses, and as Zaphod shone a torch into it, little was visible in the dusty gloom.
"According to the legends," he said, "the Magratheans lived most of their lives underground."
"Why's that?" said Arthur. "Did the surface become too polluted or overpopulated?"
"No, I don't think so," said Zaphod. "I think they just didn't like it very much."
"Are you sure you know what you're doing?" said Trillian peering nervously into the darkness. "We've been attacked once already you know."
"Look kid, I promise you the live population of this planet is nil plus the four of us, so come on, let's get on in there. Er, hey Earthman ..."
"Arthur," said Arthur.
"Yeah could you just sort of keep this robot with you and guard this end of the passageway. OK?"
"Guard?" said Arthur. "What from? You just said there's no one here."
"Yeah, well, just for safety, OK?" said Zaphod.
