"Murrr..." Jack said to his neighbor, not having anything coherent to say. Not as if he could say it coherently if he wanted to. It just all came out sounding exactly the same, an indistinguishable 'murrr' sort of sound. With the occasional moan or gurgle for color.
He shuffled along in step with the rest of the crowd, not entirely sure what they were doing or where they were going if they were going anywhere. Not that he cared. He was with others of his own kind, he knew it, and that was where he belonged.
"Murrr, gurrrbul, murrr," he said again to his neighbor, as if trying to ask what they were to do next.
