In Mister Rogers' Neighborhood, Bob Trow is a creative craftsman who constructed the miniature models of Make-Believe and other surprises in his workshop. His warm relationship with Mister Rogers highlights giving, receiving and sharing -- parts of a rich friendship.
In Make-Believe, Bob Trow plays two additional roles: Bob Dog, a loveable and rather timid dog who likes to howl, and Robert Troll, a gibberish-speaking troll with an affectionate sense of humor. His unique "trolltalk," like double-talk, is similar to children's play with nonsense syllables as they experiment with language and sounds.
