You've crash-landed on a planet ship far far away from home. The planet's native aliens, the Koo-Sai, are delighted to have a mysterious Hoo-Man to study...  you're much more exciting than the local flora!
You arrive at the lab for another day of exams to meet Lupine, a friendly Koo-Sai researcher determined to find out just how long a hoo-man can last when met with Koo-Sai pleasure techniques!
