Pig Whistle

The Tin Woodman is almost lost forever when the Nome King transforms him into a whistle in the shape of a little green pig and adds him to the enchanted bric-a-brac in his underworld palace. However, little Prince Evring carries him out of the underground caverns in his pocket, and Billina, realizing that this is the Tin Woodman in enchanted form, restores him to his natural form.
