When the class goes on a field trip to destroy a forest, Thrasher befriends and hides a talking plant. Said plant turns out to be the spirit of Insanus' natural world, and wants robotkind's total destruction.
Examples:
- Gaia's Vengeance: As the robots have purposefully stripped Insanus' natural life down to nothing, the Green Spirit wants to wipe them out in reveenge and spends most of the episode trying to obtain a special ball of super-fertilizer, which allows her to grow to colossal size and go on a destructive against robot-kind.
- The Ludovico Technique: After they find Thrasher helping out a plant, his friends and the Gore-Ax force him to watch propaganda movies to brainwash him into hating plants. Since they cannot find the right video (the one they initially used was a Twilight parody that the Gore-Ax called "[the movie] that makes you stupid"), they use one about "talking trains" instead.Thrasher: I'm a steam train and a really useful engine.
- Shout-Out: On their field trip, the students are met by the Gore-Ax, a pardoy of the Lorax who unlike his namesake serves as a destroyer of trees.Gore-Ax: I am the Gore-Ax! I hack through the trees!
- Special Guest: Lewis Black as the Gore-Ax/the Scrap Metal Spirit of Insanus and Lisa Lampanelli as the Green Spirit of Insanus.
- Take That!: To the The Twilight Saga. Thrasher is forced to watch a movie that shows the danger of plants. Instead, we get a robot version of Twilight and this line:Gore-Ax: No, no, no, no. This isn't the movie that makes you hate plants; it's the one that makes you stupid!
