Yip Yips facts for kids

Kids Encyclopedia Facts

The Yip Yips (also known as the Martians or aliens) are characters on the American educational children's television show Sesame Street. They are interplanetary visitors, from the planet Mars (in one of the first skits, as soon as they descend, their first words to each other are "...Not Mars." "Nope."). These creatures, with squid-like tentacles, large eyes, and antennae, materialize into a room and say, "Yip-yip-yip-yip... Uh-huh", in monotone voices. They come across common objects and, curious as to their names and functions, the Yip Yips consult a book they call "Earth book" which presumably contains information about things on Earth. For example, in one skit the Yip Yips try communicating with a telephone by common greetings such as "Hello", "Greetings", and "Hi there!" unsuccessfully. After each failure they say "nope nope nope". Next they address the phone as a cow, a cat, and then a chicken, only finally learning what it really is when it rings. They "ring" back at it with their voices, clearly pleased to have identified and established communication with it.They marvel at devices such as clocks, telephones and computers. When frightened, each covers its face with the lower part of its jaw while making a distinctive "goom" noise.

In one skit, they struggle to decide what to do with a book, possibly not having acquired their "Earth Book" yet. After trying to eat, smell, and hear the book, a wind picks up and opens the pages. After the Martians had recovered from their shock they began to read the words.

Built by Caroly Wilcox, they are "Yip Yipped" by multiple muppeteers including Jim Henson, Frank Oz, Jerry Nelson, Martin P. Robinson, and Kevin Clash. The puppets have a very simple design, controlled entirely by two rods (one for the body and eyes, the other for the front of the mouth). This allows their entire bodies to be seen on camera, appearing to float in the air.

The two Yip Yips seen most often are called "Bob" and "Joe". On the Dutch version, Sesamstraat, the Yip Yips are called "Sjoerd and Hendrik Marsman", referring to the early 20th-century poet Hendrik Marsman. Note that in Dutch, Marsman does literally mean "Martian".

Merchandising

Around the time of Sesame Street 's 35th anniversary, licensors finally started to notice and recall the characters. In mid-to-late 2003, Hot Topic led the way with the first-known official Yip Yip merchandising, a "vintage"-look T-shirt with two Martians. This was followed in the fall of 2004 with Gund bean-bag toys. Light switch plates, action figures (by Palisades Toys), and stuffed toys followed. The 2006 Sesame Street calendar features the Yip Yips for November, and they make an appearance on the front cover. Costumes of the characters may be purchased, but these may not be authorized by Sesame Street.

The only real acknowledgement of the characters previous to 2003 was their mention in the 30th anniversary book Sesame Street Unpaved.
