You’d all done your part to retrieve the parts (or at least most of you), and once together, they were simple to assemble—in fact, they near about assembled themselves. You could have guessed you were dealing with some sort of cat, but it was sort of cute. At least, halfway cute.

At last, a train whistle blew in the distance. Though you could feel the beginnings of a rumble in your bones, there was no vehicle in sight yet. Little wonder, with the way the tracks wound through the trees.
As you waited, the supposed stationmaster began to click. It shifted slightly, as if orienting itself… before streeetching out as much as you’d expect a bipedal sort of cat to. It took a moment for grooming (its metal?), then stopped rather abruptly to take you in with a tilt of its head.

“So you all will be my passengers…”
After a few more clicks, it hopped over to the boarding section of the station, atop a turnstile. The train in the distance was visible now, just barely.

“First, I’d like to thank you all for putting me together! It’s a little hard to do what I need to otherwise.”

“Gotta get you onto the real ride now!”
Perhaps you should have expected the change in voice, but it was still disorienting to watch the head-halves dip back and forth.

“But now, let me introduce myself! My name is Neko-Neko, and I’ll be guiding you from here on out!”

“This place we’re in, the Infinity Train—it’s awfully confusing, isn’t it? I can’t imagine just leaving so many Passengers to fend for themselves.”
The chugging was louder now, and a breeze stirred the chilly air. A train whistle blew.

“So, all aboard, and we’ll get this explained to you in excruciating detail.”
Though you had some reservations about this strange cat-fellow(s?) you’d put together, you didn’t have all that much choice in the matter. The more normal-sized train pulled up on the tracks and came to a stop, but rather than a normal sliding entrance door, another of those red doors with the odd golden handles stood before you.

Unlike some train doors, it also didn’t open automatically. Neko-Neko fidgeted, seeming a little embarrassed.

“Well, I say all aboard, but you’ll have to open the door yourselves. We’d love to help, but, y’know.” They waved their paws. “No thumbs.”
