The Muppets slept well all that night, regardless how often the wind made the trees howl or whatever weird sounds they heard. The sun finally rose and the Muppets all began waking up and were soon back on their trek to the Emerald City Palace.
It wasn't long though that the trees, even without leaves, were so thick over them that they could no longer see the morning sun, and it got dark on them again, and finally they were stopped in the darkness when they heard sounds from both sides of the Yellow Brick Road.
On the left side, there was a thump, then a thud, and the thick grass was shifting and cracking; on the right side, there was a thud and a crackling, and then they heard the shifting of steps. Do the Muppets face the sounds from the left, or the sounds from the right?
