A childhood belief about speaking

"Mickey & the Beanstalk" was a picture book and record version of the fable (done by Disney) that was very popular in my kindergarten class in the mid 1950s. An invisible narrator recounted the drama of Mickeys plight and the dim witted giant to an invisible pair of kids -- little girl and little boy. The record beeped when you were to turn the page. Gripped with fear for Mickey's safety, I listened as the narrator whispered and the picture showed Mickey climbing up the sleeping giant's shirt to filch the key to free the harp-woman. Suddenly the little girl breaks the tension describing some NEW character that Mickey should, "leave alone!"

Who was Well Enough and how did he get in the story?!
