Deep Thought:-

Even without its data banks connected, it started with “I think, therefore I am” and got so far as to deduce the existence of income tax and rice pudding before anyone managed to turn it off.

And with that The Uuniverse thought.  Now what an interesting idea.
So in a small part of the galaxy a sentient Ricepudding came into existence.

The Ricepudding is about 5.8ft tall.
Covered in dark brown Ricepudding skin and has all the normal functions of most creatures in the universe, although somehow powered by Ricepudding energy.

The Ricepudding is a deep, thoughtful creature.  As you would expect from something that was created out of Deep Thought energy.  He is natural Phycic.

His goal is to find out why he came into existence and what his purpose is.
He is also trying to find his twin.  He know she is out there.  What she is or where she is The Ricepudding had no idea but he know she out there somewhere (she is a form of sentient income tax).
(Who said his goals had to be possible or even make sense).
