Please tell me which movie this was: It was very weird, trippy, dreamlike about a boy who enters some sort of netherland that was somewhat like a carnival or toyland. There was an attractive, young adult couple who helped him and I think they may have represented his parents or his desire for parents (perhaps he was an orphan?)
What I remember most specifically is the people in this place greeting each other with a sung, "HA-HOO." The lady explained that it was the greeting of friendshp... and love.
