The Martians, sometimes called "the Yip-Yips", are interplanetary visitors, presumed to be from the planet Mars, who are terrified by things like clocks, telephones and computers on Sesame Street. They rarely come face-to-face with other characters on the show.
In their skits, these creatures, with squid-like tentacles, large eyes, and antennae, materialize into a room and converse with each other in their native tongue: "Yip-yip-yip-yip... Uh-huh. Uh-huh," done in monotone voices. They often come across common objects and, curious as to their names and functions, the Martians will consult a book presumably containing information about things on Earth, although they sometimes make several incorrect guesses based on their book. In one skit, for example, the Martians call a computer a television and a typewriter before deciding what it actually is.
Multiple performers have taken on the characters, including Jim Henson, Frank Oz, Jerry Nelson, Richard Hunt, Martin P. Robinson, Kevin Clash, David Rudman, Julianne Buescher, John Tartaglia, Eric Jacobson, Matt Vogel and Leslie Carrara-Rudolph.
The first puppets were originally chenille hats, adapted by Caroly Wilcox.
|Picture||Summary / EKA||Description|
| Grandfather clock |
|The Martians discover a grandfather clock and wonder if it's an Earth person. They consult their book, which says a person is tall, has a face, and has hands. The clock fits the description perfectly. But then the grandfather clock begins chiming the hour, frightening the Martians.|
| Telephone |
| The Martians discover a telephone. They say hello to it, and then try mooing, meowing, and clucking at it. None of these bring any response. Then the phone begins to ring. The Martians, thinking it's talking, start making ringing noises back.
| Was Bert captured by Martians? |
|Ernie wakes up and tells Bert it's time to get up, but notices that Bert isn't in his bed. He slowly ponders what happened to his best friend, coming to the conclusion that maybe some Martians took him away in their spaceship. As it turns out, Bert just got up early to fix some oatmeal. Ernie is relieved... until a real spaceship lands and the Martians enter the room.|
| Radio |
| The Martians discover a radio. They tune into three different styles of music, none of which they like. Then they tune into some static, which they start joyfully dancing to.
| Sesame Street News: Old MacDonald had a spaceship |

Around the time of the 35th Anniversary of the program, licensees finally started to notice and recall the characters. In the latter half of 2003, retail outlet Hot Topic led the way with the first-known official Yip Yip merchandising, a "vintage"-looking t-shirt with two Martians (pictured).
This was followed in the fall of 2004 with Gund bean-bag toys (pictured).
In 2008, a second t-shirt was made by Mighty Fine featuring the same artwork as the Hot Topic shirt, but retaining the two puppets' original colors. More t-shirts eventually followed.
Light switch plates and other merchandising were released featuring a vintage art style created for many of the characters in conjunction with the anniversary celebration.
The 2006 Sesame Street calendar features the Yip Yips for the month of November, and they make an appearance on the front cover scene.
Two Martians appeared in "Out of This World", a Sesame Street Live touring show that launched in 2003, and featured in the song "The Yup Yup Boogie." They also make appearances in the CD-ROM game, Get Set to Learn!, during Zoe's "What Size is Your Prize?" game and the CD-ROM Elmo's Reading Basics. They also star in an online game at Pbskids.org, Earth Exploration, where they observe nature with their talking guidebook.
In 2011, the Martians were featured on iYip, a soundboard iPhone app in which the Martians recite random phrases and statements. (Martin P. Robinson and Matt Vogel provided the Martians' voices for the app.)
