An imaginary creature from a world that I am building these days for the GURPS role-playing game that I am GM'ing for my brother, cousin and a very close friend... both of the last two as close as brothers actually. BroGURPS.
The animal is harmless, about the size of a squirrel and inhabiting about the same ecological niche, it's ugly, has a strange name, and is a nut eater.
The head is the most alien about it. It has a face turned towards the ground which is mainly used for eating. On top of this it has another head which is mostly sensorium to spot enemies and with some small manipulative arms. Of the order Oktotaupi (yes there are more coming).
Tolkien made everything much easier for himself by using horses, ravens, and all sort of other animals already present in England.
