From the opposite direction came a larger black spider-like object. It zapped past them.
“And that was…?”
“A Frogstar Scout robot class B out looking for you.”
“And that?” said Zaphod, as a third one seared through the air.
“A Frogstar Scout robot class C out looking for you.”
“Hey,” chuckled Zaphod to himself, “pretty stupid robots eh?”
From over the bridge came a massive rumbling hum. A gigantic black shape was moving over it from the opposite tower, the size and shape of a tank.
“Holy photon, what’s that?”
“A tank,” said the man, “Frogstar Scout robot class D come to get you.”
“Should we leave?”
“I think we should.”
“Marvin!” called Zaphod.
“What do you want?”
Marvin rose from a pile of rubble further down the corridor and looked at them.
“You see that robot coming towards us?”
Marvin looked at the gigantic black shape edging forward towards them over the bridge. He looked down at his own small metal body. He looked back up at the tank.
“I suppose you want me to stop it,” he said.
“Yeah.”
“Whilst you save your skins.”
