Did you hear what happened to Nat.....
So his dad wanted to show him a tour of where he works, at the gas treatment plant.
So Nat was just trotting along with his dad, and when his dad was talking to an employee, he thought it would be fun to hide in another room.... Well, he hid in the gas exhaust treatment room, so he was breathing in gas fumes for about five minutes in an air tight area, finally he came out feeling sick and went home.
When he was home, he felt a bit better, so he and his friends decided it would be cool to smoke some cigarettes out in the woods.... well, that gas was still trapped in Nat's body, and when he lit up that cigarette, he exploded.
There hasn't been much news on it,they want to keep it on the downlow. At the moment they have been using a biomechanical robot clone to replace Nat.
Quote from the producers- "We are well aware that the absence of Nat is a devastating tragedy, but we assure the fans that Robo-Nat will do a perfect job at replacing him, we assure that the robot has studied all of Nat's actions and facial gestures and does an even better job at acting than his organic precede."
