Fred Rogers

Fred Rogers is a special guest star because he comes from his own PBS program: .

He is an old friend of Arthur's mother, and knew her from when she was a little girl. He stayed for a few days at Arthur's house in "Arthur Meets Mister Rogers." He meets people and walks around Elwood City, even visiting Arthur's school before he had to leave. He gives Arthur some helpful advice about not being afraid.

He was also seen in the episode "Elwood City Turns 100!", as one of the many guest stars that Muffy invites to the play. However, like the other guest stars, his voice wasn't heard.

Buster mentions him in "On This Spot" after his Derek Montaigne tour fails. He desperately tries to keep the crowd following by telling them "Mister Rogers once stayed there."

Fred Rogers died in 2003 from Stomach Cancer. He is one of two Arthur guest stars who have passed away, the other being Koko Taylor.

Go-Stop-Go
In the Mister Rogers' Neighborhood Season 29 episode "Go-Stop-Go", Mister Rogers visited Marc Brown to see how a cartoon is animated, and Arthur himself visited the Neighborhood of Make-Believe.
