Mr. Rogers visits Marc Brown, creator of the Arthur book series and shows him how he draws Arthur. After explaining how the TV show is made, they watch a clip of the episode "Arthur Meets Mister Rogers", which Rogers himself guest-starred on, and meet Michael Yarmush, who does the voice of Arthur and Arthur himself shows up in the Neighborhood of Make-Believe, greeting several neighbors — including Lady Elaine. Rogers views a video on how traffic lights are assembled.
