Kermit and Fozzie's Dad is the father of both Kermit the Frog and Fozzie Bear in The Great Muppet Caper. An old friend of Mike Tarkanian, he is only glimpsed in a photograph, with the implication that he is now deceased. Tarkanian puts the picture back in his desk before firing the pair, as he "doesn't want him to hear this."
Dad resembles Fozzie, but with green fur and Kermit's eyes and collar, and is apparently some unusual amalgam of bear and frog. The View-Master reel put it more directly: "Their father was a green bear."
