An 'RPG' of sorts written by Samuel Clemmens, Owlbears is an excuse to run around in owl masks pretending to be a ninjas. You are a half-owl, half-bear. You are king of the forest. There is a castle. It has many guards. You'll need powers if you want to sneak in. Not much more needs to be said. Rules include ganging up on crybabies, hitting things with your mighty claws, and NEVER SITTING AT TABLES. This is the game you play while waiting for Axe-Cop to update.
Rules can be found here, if you dare.
Not to be confused with Owlbear, the classic D&D monster.
