 The voice unit was the very same one that had been introduced in 1960 inside Mattel's Chatty Cathy doll, and used in all other Mattel talking dolls and toys.Kiddles were made of soft vinyl with painted facial features and rooted, brushable hair.The first, second, and third series (called "bigger bodies" by collectors) ranged from 2¾ in to 3½ in, while the Skediddle Kiddles were 4 in tall and had a special mechanism inside the body which allowed them to walk, wave, and ride vehicles with the push of a child's hand.
