Tahn-Enn-Bahm also known as the Christmas Tree from another World is a treelike alien. He is from a world whose name humans can't pronounce. He was sent to find out the human race's weaknesses so that they can rule over them. Lisa tried to chop him down but wasn't able to bring herself to do it because she refused to kill even a plant. When she tried to tell the truth, no one believed her. He was later accidentally electrocuted by Homer.
