Meister Eder und sein Pumuckl (1982)

The adventures of an old fashioned master cabinet maker in Munich and the tiny red-haired goblin Pumuckl, who becomes visible to him when he gets stuck to the pot of glue in his workshop. The tiny creature is visible to nobody else and full of mischief, and hilarity ensues as objects are seen moving around and the elderly craftsman seems to be talking to thin air.
