Piper in the Woods

In "Piper in the Woods", an army doctor is asked to treat a soldier from Asteroid Y-3 who claims he is a plant.

This wouldn't be a problem, but the soldier is incapable of any physical activity, preferring to stand still and point himself towards the sun.

When more soldiers return from Asteroid Y-3 also claiming to be plants, Dr.

Harris travels there to investigate.

While there, he learns about a mysterious indigenous people living in the woods called "Pipers", who might be able to shed some light on the subject.
