Rogers plays with a toy boat. Trolley shows how it will be the waves for the opera.
In the NOM, Lady Aberlin gives Trolley its costume. Corny thinks he sees waves; he hadn't heard about the opera. He'd like to be in it. Grand-père gives Reardon a boat in return for a song. Because there are twelve people in the opera, they will need a lot of room for the production. They decide to use the whole neighborhood. Grand-père is handling decorations.
Songs: Won't You Be My Neighbor?, Just For Once, I Am A Teddy Bear, Tomorrow.
