"You know what we seek?" The Spine asked the cat.
"Yes."
"You know where it is?" Rabbit asked.
"Yes." The Cat grinned wider and walked towards them. "Would you like me to show you?"
"We'd appreciate it Mr. Cat." The Spine said. "Though, we don't have much in way of barter, for your time."
"That's alright." Cat purred. "And I'm not really a cat. But anyway, follow me, and I'll show you to your hat."
"So..." Rabbit asked. "You're not a cat...what are you?"
"I'm not sure, but I'm not a cat."
"How long have you been in our brother's hatch?"
"Always." It purred, it's eyes a-glowing. It said not more as it lead them on, and didn't say anything by way of a name, so they could only refer to it as Mr.Cat.
After sometime, Mr.Cat led them to the hallway with doors, and deeper than either robot had gone before. Eventually the blue-purplish mist returned, but they kept close to their guide, who only said it wasn't much farther.
The doors began to change colors, from strictly red to orange, and pink, and yellow, and black. A slew of others, and still the cat went on. Eventually telling the two robots it was around the corner.
A multicolor door. Like one of those horrible tie-dye shirts that Peter VI was obsessed with when he was a boy.
"Here you are."
"Behind this door?" The Spine asked.
"Yes."
"Okay, well, thank you Mr. Ca-er, Mr. Creature."
"My pleasure." It purred, staying with them.
The Spine turned the handle, and peered inside. It was dark, save for a single light bulb, hanging over a single can of soup. Tomato soup to be exact.
Rabbit peered in next to him. "Mr. Cat, there's only a can of soup."
"Yes?" The Cat-like-creature answered, eyes fixed on the robots. "And, I'm not a cat."
The Spine reached inside the dark room, and took the can, thinking it might be an Indiana Jones type thing, and his fedora would fall from above if the soup was moved.
But that didn't happen. A closer look at the can revealed it was just a can. Probably from the Walter Kitchen. Of all things.
"Er, Mr. Creature, this isn't my hat." The Spine said, politely as he could. "Is it somewhere in the room?"
The cat-like-creature just stared, expectantly. The Spine matched his stare for a few minutes, then realized what it was waiting for.
Transforming one of his metallic fingers into a can-opener tool, he opened the soup and sat it down in front of their odd guide, who began licking it up, throwing thankful glances to the tall robot.
"Now then," Mr. Cat licked his lips, now finished, "your fedora?"
"Yes?"
"Follow me."
"Again? Listen, Mr. Cat-Creature, if you're hungry you can live with us at the Manor."
"No, really, I know where your hat is. I prrrromise." It purred. "I puuurrrrrrr-"
"Okay, we believe y-y-you!" Rabbit stopped it.
"Good." Mr. Cat-whatever-he-was, stretched and then bade the robots to follow him again. The farther they went, they noticed this blue and purple mist seemed to go from swelling around them, to clearing completely.
