Kasper und die Heinzelmännchen (1968)

The journeyman tailor Kasper has a hard time. His mistress is constantly keeping him busy with chores. When the brownies show up in town and take over all the craftsmen's work, Kasper can no longer get any sewing done. That's fine with the master. He now often meets up with his colleagues to sing a quartet, but Kasper finally becomes the master's pet. When this nosy and bossy person ambushes the brownies with peas, the good Kasper tries to protect the little gnomes from harm. He is unsuccessful, and the brownies leave the town for good, badly demolished. Now they have to do the work themselves again. The masters are very sad, but the choir singing helps them get over the worst. Kasper is happy, he can pick up the needle again and become a capable journeyman tailor.
