One with a king that gets taken through a door by a huge black glob.
There's a king that gets taken through a door by a huge black glob/smoke thing and a little boy and the kings daughter try and save him. The door that held the black glob had been locked up but the little boy unlocked it not knowing what was behind the door. And I thinly there was a toy train in a little part of the movie that everyone could ride on.
