∞ Tumbleweed as Dodgeball
A tumbleweed is a structural part of the above-ground anatomy of a number of species of plants, a diaspore that, once it is mature and dry, detaches from its root or stem, and tumbles away in the wind.
You can find tumbleweeds tumbling along I-5. They are impressive and fun to see from your high speed vehicle. You can even play dodgeball.
