Today is opera day! Mister Rogers shows flash cards and talks about concentration.In the Neighborhood of Make-Believe, Reardon is teaching Henrietta to concentrate. This provides the introduction to the opera. Betty Aberlin interferes with Francois Clemmons and Yoshi Ito’s badminton game. When they tell her to go away, she tells them they will be sorry. Lady Elaine teaches her to make snow. Yoshi and Francois are turned into snowmen. Reardon teaches Betty to concentrate so she will remember how to melt the snow. The formula calls for a very special teacher, Reardon, and a warm pussycat, Henrietta. With the help of Audrey Cleans Everything and Chef Brockett, the snow is melted.
