Dunderklumpen!

Description by OLDIES.com:

On an evening in northern Sweden, during one night when the sun partially sets only one way, the animated character Dunderklumpen comes from the woods to seek some friends to keep him company. In the Wolgers family home he finds toys belonging to a girl named Camilla and a boy named Jens, and brings them to life, whisking them away to the woods where he lives. This crew includes a little scaredy-cat lion named Lionel, the demanding doll, the cute harmonica-playing bear Pellegnillot, and Dummy the bunny. Jens sees the kidnapping after hearing the toys' cries for help and follows Dunderklumpen, who is not so quick to surrender his newfound company.
