BabyCo is the world's leading manufacturer in baby products. However, what the public doesn't know, is that Drs Kinder and Heep, two of its most brilliant scientists, are tirelessly working in complete secrecy to crack the indecipherable code to 'baby talk': a highly sophisticated language, and the key to the secrets of the universe. Before long, problems arise when mischievous Sly, the smartest of the toddlers, escapes confinement, bent on uniting all babies to free those trapped in the laboratory. Now, Kinder and Heep must find Sly before it is too late.

After squandering his grant money, despondent and recently widowed anthropologist James Krippendorf must produce hard evidence of the existence of a heretofore undiscovered New Guinea tribe. Grass skirts, makeup, and staged rituals transform his three troubled children into the Shelmikedmu, a primitive culture whose habits enthrall scholars. But when a spiteful rival threatens to blow the whistle on Krippendorf's ruse, he gets into the act as well.
