Welcome to Muppet Wiki!
Freddy is Telly Monster's doll. According to Telly, Freddy worries even more than he does.
In a 2006 episode, Freddy appeared on the show as "Fantastic Freddy", the doll's superhero persona. He is eventually joined by Zoe's pet rock, Rocco, and together they "save the world" from the Dastardly Dinosaur (as played by Baby Bear). Fantastic Freddy even has his own theme song.
