The Tree of Blight is an evil tree that appears in the episode "Hug Wolf." It spews out evil juice every one hundred years and was attacked by Finn and Jake. It was burned down by Jake, but in the explosion that followed, a piece of the Tree's flaming remains had hit the Alpha Hug Wolf and possibly left its evil mark/curse on her.
The Tree is alive and has a dark color to it. Its branches resemble tenticles and its face is long and pointy with a bright green color in it. Its roots stick out on the ground.
- Blight is a word for sickness, often affecting plants and trees.
