I;m looking for a cartoon movie it might be a short film. I can't remember the title or much about the plot. It has something to do with a boy who goes into a garden or a greenhouse and he makes friends with someone maybe a fairy. I saw the movie before 1995 and it could be made in any time before that as far as I know.

Could it be Thumbilina?

The movie you are asking about is called a journey through fairy land. The premese of the movie is about a boy who is kicked out of his band for not playing what the teacher wants him to play. He spends time in his greenhouse playing on his instrament when a blond fairy befreinds him and takes him to her world. He along with her and many friends have to work togeather to save her world.:D

I think its bob the builder
