Hello. I've been trying to find this children's cartoon movie I watched with when I was little. Im 20 now, I have no idea when the movie was made. It was about a boy name Mimo. His bed flew, and took him into a different world, where there was this king. He did something causing this deadly river of black tar to come rolling throw the castle.

I loved this movie. Im thinking it was called the Adventures Of Mimo. But I can't find it anywhere. Can anyone help me?

Could it be Nemo?

Little Nemo: Adventures in Slumberland (1989) (http://www.imdb.com/title/tt0104740/)

Oh thank you! I've been trying to find this movie for so long.

The title of that movie is Little Nemo
