Walks onto pitch with barrel of water, dumps it… wins. 
This competition does seem sort of “I drink your milkshake”… er, worm-shake ish. Vibration and sound travels a lot farther than each person’s allotted area, so the tympanist, shovel-whacker, clarinetist, pitch-fork tappers, and Morris dancers are all affecting each others’ worms.
Someone should study the worm-depth intersection of all these noises to find out what actually happens down there.
