The lyrics of their songs are often humorous, tongue-in-cheek critiques of German government or society.
The group's most popular singles have been "Millionär", "Küssen verboten", "Olli Kahn" (about German star World Cup goalie Oliver Kahn) and "Deutschland".
In reference to the group's name and the Brothers Grimm fairy tale "The Frog Prince", the group's logo is a green frog wearing a crown. The frog logo has appeared in a number of album and single covers.
