Babies are hardly monster-like, unless you're a toy. After escaping a drooling baby, Tinny realizes that he wants to be played with after all. But in the amount of time it takes him to discover this, the baby's attention moves on to other things only an infant could find interesting.

Tin toys on display at a Japanese Tin Toy Museum circa 1985, fancifully photographed and accompanied by twinkly background music. The collection is broken into 10 categories - 1900-1945, 1945-1949, 1950s, battery toys, monster toys, Pierrot toys, car toys, motorcycle toys, robot toys, and space toys.
