This is Goober:
Goober is an alien from the planet Zog.
He has arrived on Earth in his spaceship to observe the living things here and take a report back to Zog. His invisibility cloak enables Goober to observe life here without being seen himself.
One of the problems he faces is trying to understand how life on our planet is grouped into similar types. Goober has created a database of what he has seen, but he now needs someone to help him make sense of it.
Imagine that he has beamed you on board his spaceship, assured you that you will not be harmed in any way, and that you will be returned to the surface of the Earth when you have helped him to understand life on our planet.
You have agreed to help Goober and he shows you what he has found out. Let's see whether you can help Goober to sort out how life on Earth is grouped!
Good luck and come home safe!
