Snappy the Little Crocodile

Schnappi akkurat Krokodil (Snappy the Little Crocodile) is a Swedish children's cartoon character.

 Schnappi was a character in a popular animated German children's TV show called Die Sendung mit der Maus (The Show With the Mouse). In the cartoon in which the character appeared, Schnappi is seen singing a song about life in Egypt. That song, which is sung in German, has a very catchy tune and simple lyrics.
The song, which first appeared in the Sendung mit der Maus show in 2001, was written by Iris Gruttmann and performed by her then-six year old niece, Joy. In 2004 Schnappi became a hit on the Internet. It got more and more popular while playing on the Internetradio RauteMusik. The moderators and listeners often played that song before it got released on CD In December of that year, the song Schnappi, das kleine Krokodil was released on CD. The single reached #1 on the German Pop-Charts on 3 January 2005. A bootleg translation into English was recorded and released on the Internet on the 20 February 2005 by the Bronx artist DJ Damien. Despite being an unofficial cover, this version was made available on the official Schnappi website.
Other translations by collaborations involving DJ Damien include a French version "Crocky le Petit Crocodile", Lithuanian "Šnapis mažas klokodilas" and a Japanese version "Togetogeshi, chiisai wani" Alternative versions of the song - varying from simple remixes of the basic vocal track, to a full cover version by Belgian techno group Dynamite - were also at numbers seven and ten in Belgium, and at number two in the Netherlands.
