Tree

Tree is a minor, one-off presence in the sprawling universe of Futurama, the kind of background gag the show tosses off without ceremony. Voiced by Billy West, who gives life to half the cast, Tree exists mostly as a punchline rather than a fully drawn character with wants of its own.

The joke of Tree is really the joke of Billy West himself — an actor so versatile he can be handed literally a tree and make it sound like it belongs in the world. It works because Futurama trusts silliness to land without explanation, and West's commitment sells even the smallest bit.
