The names also live on because many people have named their pets after the anti-heroes from the children’s series. In addition, the expression ‘Toet toot boing boing’ from the title song by Peppi and Kokki is still frequently used in the media, Den Boon notes. “It’s often like an interjection for something that needs to be done quickly, but is often not handled too cleverly,” he explains. The tune was further developed in the mid-nineties into the house hit ‘Hakke en Zage’ by Gabber Piet.
