massive , they are , four metres tall if they 're an inch , covered in a shaggy , silvery fur with a thick , fluffed tail at one end and a pair of curved white horns at the other reaching right outta their brows and long necks that stretch down from wide shoulders to the grass of the plain below and these wide lips that mow it up as they trudge on dry ground and drink water as they cross the river and there 's thousands of 'em , thousands stretching from the horizon on our right to the horizon on our left and the noise of them all is singing one word , at different times in different notes , but one word binding 'em all together , knitting 'em as a group as they cross the plain .
