Pierce really wanted to be the conductor in their skit. He practiced really hard for the part. He was thrilled when he got it! Here is a sign he made as one of their props:
Pierce doesn't seem to have any stage fright. He spoke loud and clear as he scooted his train around the edge of the track (there was a second, smaller train that you can see along him that actually went along the track).
Afterwards, the kids took the coaches around and explained how they built everything. Pierce talked to the coaches for a long time. He likes to explain things.
