Tumbleweed

 are a miscellaneous item in Fallout: New Vegas.

Characteristics
In New Vegas, Tumbleweeds appear as balls of wheat-coloured weeds which roll around the Mojave Desert. Often they can get stuck on things, such as the buildings of Goodsprings. Give them a good kick and set them rolling free again!

A Tumbleweed is very light, so shooting it will make it fly several feet. Because a shotgun shoots many pellets at once, even more for the sawn-off shotgun, shooting it with one will commonly send the tumbleweed flying into the sky so far that it usually disappears from sight before it can be seen landing.
