A charming, cautionary tale for children about the perils of going to bed with gum in their mouths, Wanda and the Oblahlahs tells what happened to Wanda when she doesn't heed her mother. Diligent about throwing her gum away when her mother and father remind her, Wanda, left to her own devices with the babysitter when Mother puts on a red dress and goes out to dinner, leaves her gum in her mouth and suffers the consequences. The Oblahlahs, a curious group of little party animals, come to life in her mouth and take her voice, leaving her only able to say, Oblahlah, Oblahlah, until even her faithful dog Moldy won't play with her anymore. When the doctor can't save Wanda's voice, her mother, father, brother, and even Moldy do what they can to help, but it's up to Wanda to learn to do what's right with her gum and get her voice back.
