In the beginning Master, Bad Boy hops on the Bad Boy Train with a briefcase full of Bad Boy (Btw bad boy is a bomb type of liquid where if you put water on it you and everyone dies) and gold. Soon Master Bone steals the package and takes it to the driver of the train who has wanted it for a while. The reason Master Bad Boy was on the train was to get the bad boy and gold to the president would hide it in a vault, because if the wrong person got in the world could end. Then Mr. Bone gives it to the conductor.
And then the conductor gets it and everyone gets eliminated/unlived/game ended/backstabbed.
The end.
