Looking for a 80's 90's movie about a boy who shrinks to the size of a mouse
In the 90's I saw a movie at school, which was displayed on a big screen (which was kind of new back then).
The movie was about a boy (or perhaps girl) who found a mousehole unde his bed. Besides the hole was a nail, after touching the nail he shrunk to the size of a mouse. He made friends with the mouse and had some adventure in the mousehole.
I'm certain it was not an animated movie.
Can someone help me with the title?
