I saw this movie when I was little and I don't know the name of it and barely remember what the movie is about. It's been driving me insane for years!

All I remember about the movie is its live action some of the movie, then this young boy goes down a hole in the ground and comes into this cartoon world of freaky looking monsters. I believe it had weird songs and the colors and monsters were kind of weird.

It gave me nightmares as a kid because it was so weird..

I know it's NOT James and the Giant Peach, Labyrinth, Little Monsters, the Goonies, the Yellow Submarine.

Please help!!

Coolworld maybe?
