Babes in the Woods.

Two Dutch children stumble on a clearing in the woods where gnomes are going about their business. The gnomes are friendly to the children. A witch comes and takes them away on her broom to her gingerbread house, where she turns nasty on them, turning the boy into a spider, her yowling cat to stone, and tries to turn the girl into a rat when a gnome's arrow stops her. While the gnomes are fighting the witch, Hansel and Gretl free the other children who have been imprisoned and transformed by the witch.
