What is "robby"

Robby is a 1968 family film written and directed by Ralph C. Bluemke. It is a modern-day retelling of the Daniel Defoe novel Robinson Crusoe in which the main characters are portrayed as children. The film deals with many themes, including friendship, homesickness, racial blindness and naturism. It is unusual for a family film in that it contains extensive, explicit nudity involving young boys.
