Tahn-Enn-Bahm

Tahn-Enn-Bahm, also known as The Christmas Tree from another World, was an evil tree-like alien from a world whose name humans can't pronounce.

History
Tahn-Enn-Bahm was sent to Earth to find out the human race's weaknesses so his race could rule over and enslave them. He was bought by the Simpson family at Krusty's Kristmas Kut-O-Rama when they were looking for a Christmas tree.

When brought home, he revealed his plan to Lisa who was unable to get help as no-one believed her story. The next day Homer dropped a bucket of water on a plug socket powering the Christmas lights and Tahn-Enn-Bahm was killed. This resulted in his race leaving Earth in fear.
