 In the last season, Beaver, arguing with Wally as the two are walking home, pushes Wally into the street and they start chasing each other around a tree and into the house.The show's opening and closing sequences are accompanied by an orchestral rendition of the show's bouncy theme music, "The Toy Parade", by David Kahn, Melvyn Leonard, and Mort Greene.For the third season, the tempo was quickened and the tune whistled by a male chorus over an orchestral accompaniment for the closing credits and for the production credits following the opening sequence.
