Strange Encounters

"This place is boring," said Richard.
"Too drab," said Susan.
"Their interior designer should be fired," said Janet.
"It sucks," said Devon.
As they stood there they were suddenly startled by the appearance of an unexpected inhabitant of the place. They had been alone for a long time, all by themselves. They had not seen any actual inhabitants of Murloch at any time so far in their trip.
A huge, spherical, grossly overweight humanoid cyborg waddled up to them and spoke:
"Your pants. May I have them? Would you remove them for me please?"
The fat cyborg looked at each of their faces. Sensed that they would not be soon complying. Or that perhaps they didn't understand him. He frowned. Tried again to communicate with them.
"Either that or your skirts or slacks. Would you find yourself taken aback a bit if I or someone else we authorize were to take the opportunity to add them to our large and growing collection?"
Then the incredibly fat, highly-spherical humanoid cyborg thing quickly turned around and ran off down the corridor and around a corner.
As they got used to his sudden disappearance, somebody (or something) else appeared.
An incredibly tall and thin android, painted all white with thin red pinstripes running vertically along his shell. He ran up to them and addressed them as a group.
"Slack. I'm looking for slack because I need it, see. So do you know of where I could get it, please? Could you point me in the proper direction at this particular moment in time? Are there places where one could rent it temporarily or even extemporaneously?"
Richard shrugged. "Uh, maybe?"
The incredibly tall, thin android-man frowned, paused for a second, and then quickly turned around and ran off down the corridor and around a corner.
