ADVENTURE: The Earth Rangers is a hugely successful non-profit organization that reaches out to kids all across the country. Their mandate is to teach kids about our environment and how to protect animal habitat. Chuck and Andy spend a day learning how to be Earth Rangers... and become the stars of the "after-show" Earth Rangers presentation. THE LAB: Dr. Greenie comes up with a new invention that creates a protective force field around animal habitats. While the idea is good... it backfires when GP is stuck in a Mimes' glass box for the entire episode.
