Tumbleweed Of The Void

So empty...

A little tumbleweed that comes in and tumbles to emphasize the emptiness of an area. Said area must be outdoors for this joke to make sense (although this isn't always the case), Superb Spacetiming is required for it to work, and the only characters that are allowed to be in the scene are the ones who newly arrived to see its emptiness for the whole gag to be valid. These characters rarely acknowledge the tumbleweed's existence, and the plant just as rarely interacts with its surroundings.
