Mister Rogers' Neighborhood S04 E09 Castle Waterfall Pt 4

"Won't you be my neighbor?"

Rogers needs a washer for a fountain he wants to assemble. Instead of taking one from Bob Trow's workshop, he merely leaves him a note. In the Neighborhood of Make-Believe, the Castle fountain works only to a small extent. Lady Elaine has taken the windmill at Someplace Else apart for unknown reasons.
