[ULFGARD]

Okay, so long ago I had a rather silly character who had a riding rabbit. The thing had blunt claws and good night vision, and required the skill Riding (Riding Rabbit) as well as a special harness. It was a slightly better jumper and not as good for endurance, as I recall. It was 3d edition, though, and I have no stats for it any longer. It did once get in a fight with a warhorse, and having claws, it was rather nasty. However, scaling issues caused us to not including super jump.

The largest effect it had? EVERYONE noticed it. Worse: many wanted to STEAL it. So the fluff parts had some important in-game consequences, just as showing up in a perfectly "legal" speedo to work would cause some interesting "at work" consequences (blindness for coworkers, probably some sort of sexual harassment training for me).
