According to Muppet Wiki, "The Martians are interplanetary visitors, presumed to be from the
planet Mars, with squid-like tentacles, large eyes, and antennae, who converse with each other in their native tongue: 'Yip-yip-yip-yip...Uh-huh.
Uh-huh,' done in monotone voices. They're usually terrified by things like clocks, telephones and computers. They also rarely
come face-to-face with other characters on Sesame Street." Caroly Wilcox developed the first Martian puppets that were originally
chenille hats. More pictures of the Martians from the 'Others' section of Sesame Street will be added to
the section soon.
