I adore cooperative writing and I think my favourite remains Star Trek PBeM groups purely because everyone knows Trek and it's just so open ended you can do pretty much anything.
The ship I'm on is the USS Spectre, Captained by the wonderful Alan. At some point in Alan's weaker moments, he thought letting me add a rabbit personality to the ship was a good idea. Mark the Bunny is a houdini. He has a thousand ways of escaping the Captain's quarters and getting out and about the ship. In this case, he's managed to end up in engineering. The problem is, the two feet are all suffering from hallucinations, one Ensign Frost thinks Mark is an evil overlord.
(USS Spectre - Main Engineering – Mark the Bunny - 1930)
Frost whispered to the little bunny, "You can't talk I hope, you are just a little normal fluffy thing. But if the rabbit invasion is coming. I am on to you, and I will stop you."
There was probably a universe where Mark was sapient and would understand such threats. In such a universe he was probably leading such an invasion if not plotting the domination of the galaxy. This universe, however, had to settle for a vaguely sentient rabbit who just expected for everyone to do what he wanted and had no real way to enforce that expect through passive aggressive peeing and general stubbornness. It was ridiculous how disorganized two foots were and Mark was forever trying to train them to the bunny method.
He was carried to a different part of Engineering and the two foot sat down, giving Mark the opportunity to wiggle around so he was resting against the two foot's chest, his chin on the two foot's shoulder.
This gave Mark the ability to get pet, to watch the room for dangers and not to have any bits dangling with indignity. Some two foots just didn't know how to hold a rabbit properly!
Mark was starting to get bored. He nibbled on the two foot's artificial fur for a bit, but it didn't taste very good so instead he settled for squirming around, wriggling out of the two foot's grasp, and jumping down to the deck. He picked a direction mostly at random and made a dash for it.
