The wolf and the seven kids (1957)

One day, the Goat needed urgently to leave the house. Worrying for her children, she convinces her Goats to not open the door to anyone, especially if it is not her. And so that they could recognize her, the Goat taught them a simple song, according to which the Goats could immediately recognize their mother. But the wicked Wolf, like a thief and a bully, overheard their conversation and decided to kidnap the Goats, setting off on a trick. He asked the Bear, a forest blacksmith, to give him a thin voice to deceive the Goats, obviously hiding it himself.
