Stanley Takes a Trip -- Film Description:
"The importance of a balanced diet, told in story form for children through the medium of two-dimensional cut-out animation. Stanley is a little boy who is lethargic from lack of a balanced diet. Some animals take him for a trip on the back of a 'train engine' bull, to discover what are the proper foods for health and where they come from."
