Robot Jones just disappeared into thin air one day. I heard it had something to do with him having a human voice-over in season 2 (as opposed to the computer generated voice he had originally) and audiences reacted so badly to it they had to take it off the air before season 2 even ran all the way through?

At least Sheep in the Big City stayed on the air for a while after it was out of production. I grew to like it, too. Loved the wacky sense of humour.
