About
Treehugger Lisa is from The Simpsons season 12 episode 4. In this episode, Bart gets a job and takes Homer, Marge, Lisa, and himself to Krusty Burger. There, a group called Dirt First held a protest about killing/eating cows. The group leader, Jesse Grass, gets arrested for this but gets released. Lisa joins Dirt First and goes to a meeting. Dirt First finds out Mayor Quimby held a secret tree auction and auctions off the Worlds Largest Redwood Tree to the Rich Texan, who plans to cut it down. To prevent it getting cut down, Dirt First sends Lisa to live on the tree. Lisa goes home for a night to be warm and comfortable on that rainy night. The next morning, Lisa finds that the tree was struck by lightning. Dirt First convinced the Rich Texan to reserve the space for tree growing, but instead he makes a theme park there. Jesse Grass cuts down the ropes holding up a huge tree with a big Lisa head on it after Lisa reveals she didn't die. The tree keeps on going to this day.
