The elaborate set where Majors Healey and Nelson were practicing their survival skills with Commander Porter
( Paul Lynde ) was very elaborate to construct from scratch. Fact is that it looks very much like the
Cliff Dwelling in Mesa Verde National Park in Colorado.
The title is based on the warning found in zoos and national parks to avoid trouble with the non-human inhabitants: "Please don't feed the animals."
This is essentially a rehash of My Master, the Weakling (1967) where Don Rickles ran Tony and Roger ragged with exercises and a survival course. Even the tag is identical with a reappearance of the Naval Commander to start them all over again.
