Old animated children's movie when I was little. Help!
Its really bugging me that I can't remember the title of this movie. I'll explain what I remember.
Its about a boy and I don't remember if his father has anything to do with it. It seems he was told a story and it came true. Anyway his bed comes alive and is sent flying above the city during the night (I think there was a squirrel that tagged along) anyway he is taken to this cloud castle where the king and his daughter reside and during his stay he accidentally releases an evil darkness that overpowers the king. The boy has to save the king and the kingdom from this evil darkness.
