Help me find an old film! (tiny/dwarf boy (10cm) and a human boy)

Hello All,

Back 25 years or so, when we have a tv, There was a film showing on it. all I remember about it was that there was a human boy in his room and a tiny/dwarf boy under his bed, the boy and the dwarf becomes a friend, there was a small Ladder of matches the tiny boy used to climb, and the tiny/dwarf boy was bathing in a cup of coffee and He has a toothbrush. That is all that I remember about that film.

Hope someone can help me find it.
