Fozzie's Cousin is almost identical in appearance to Fozzie Bear. He was, in fact, made of an old Fozzie puppet that was given a bowler hat instead of Fozzie's trademark porkpie.
Fozzie's Cousin's only appearance occurred in episode 122 of The Muppet Show. From his seat in the audience, he watches Fozzie's act and tries to encourage the rest of the audience to appreciate his cousin's talent. But when Fozzie demands that only his true fans remain in the theater, even his cousin deserts him.
