Joe is Steve's brother. When Steve leaves for college on a hopscotch scholarship, Joe stays with Blue and becomes the host of the show. Joe loves squares, just like the ones on his shirt, and can't wait to play a game of Blue's Clues.
Joe's skin is a peach color. He has brown hair. His shirts' colors vary, though they all have the same square pattern.
Joe appears in many episodes of Blue's Clues. He debuted in "Joe's First Day," and was last seen in "Bluestock." He also appears in several episodes of the Blue's Room series.
