Buster's Back / The Ballad of Buster Baxter.Buster's Back: Buster is returning to Elwood City (after leaving in the second season episode "Arthur's Faraway Friend"), and while Arthur is initially excited, he worries that Buster has changed during his travels. Fearing that Buster will find him lame after his exciting travels, Arthur reads books on the places Buster has visited. When Buster arrives, he says that he did not change and was looking forward to hanging out with Arthur, and the two play checkers.
The Ballad of Buster Baxter: Buster feels left out because of the things he did not get to experience while he was away, while rumors about his travels cause his friends to consider him a snob. Arthur throws a surprise party for him, with everyone joining in to help, but when Buster does not show, Muffy thinks this affirms the rumors until they realize that they did not invite him at all. When Buster attends the party, he enjoys it and reunites with his friends. A singing moose narrates Buster's story througout the episode.
