Mister Rogers' Neighborhood (1968)

S14E4 Conflict

Mister Rogers arrives with a box of colorful blocks, which he takes to the kitchen to construct a bridge. Alongside the blocks, he has some marbles that he showcases before watching a film that explores how marbles are created and used. In the Neighborhood of Make-Believe, Lady Elaine and Lady Aberlin join Bob Dog on a journey to Southwood to uncover the truth about a situation there. Once they arrive, they discover that the components made by Corney were utilized to build a bridge, rather than for any harmful purposes.
