Mister Rogers does not change into his sweater and sneakers as usual. Instead, he sings a slightly different version of Won't You Be My Neighbor as he enters: "...a beautiful day for an opera. Would you like one? I know I'd like one..." He promptly introduces the newest Neighborhood opera: A Granddad for Daniel.

The opera opens as Grandparents' Day is underway and Daniel Mefford (played by Daniel Striped Tiger) talks with his parents about his grandfather. Daniel's father, Charles Mefford (Neighbor Aber), shows him a picture of his grandfather and reminds Daniel that his grandfather left long ago. Both Daniel's father and mother leave for the jungle -- Daniel's father, a professional polisher, on foot, and his mother (Lady Aberlin), a trolley conductor, with a few passengers on her trolley. Along with Daniel, Mrs. Mefford's passengers include a straw salesman who has traveled the world.
