I'm looking for the title of an old movie from the 80's I believe. I used to watch it as a kid, but I don't remember what the story in the movie is. I know it has a little boy and he drives a red car and there's a watch dog that follows him around through out the movie. I think some of it is cartoon and some is real people. Anyway, I would really like to watch this movie again but I need the title. So if anyone knows what I'm talking about please let me know!!

The phantom tollbooth?
