The 2005 edition came with a free storybook CD to celebrate Sesamstraat's 30th anniversary. The CD is labeled for Stemra and numbered 050905. The stories were read by Hugo Maerten, Lasca ten Kate and Esther Daems. Production for Say Cheeze BV. was done by André Pouwer.
When Malmberg started publishing the books, the content was adapted from scenes from the TV show. Most stories were written by the Dutch crew, including Chris Winsemius, Sylvia de Boer and Ries Moonen, but they also used scenes written by Sesame Workshop.
