who invited moon moon

So, at one point, there was a tumblr meme going around with "werewolf names", and you could end up with "moon moon", which became something of a meme, with the theory being that "moon moon" was a perhaps less gifted wolf who was sort of like an annoying kid brother, etc.

Well. That turns out to make a fairly plausible meta-RPG:

1. Take a game system that lets you play werewolves. Werewolf, DtD, whatever.
2. Every player makes a werewolf character for themselves.
3. The group collaboratively makes an additional werewolf character, named Moon Moon.
4. Every week, someone plays Moon Moon instead of their regular character.
5. Moon Moon's goal is to Tag Along and Be A Part Of Things. Aim for "annoying kid brother stereotype".
6. Everyone else's goal is to keep Moon Moon alive and healthy at all costs, and as a secondary thing, try to go about whatever sorts of goals they would normally pursue.

I am not sure whether this would be fun. It would absolutely require a group that can handle "it is this character's job to screw things up for the party" and still enjoy the game.
