Poehéé! Het verhaal van Sesamstraat (Poehéé! The Story of Sesamstraat) was published in honor of the 25th anniversary of Sesamstraat, the Dutch co-production of Sesame Street. The book offers a look behind the scenes, a list of performers and voice actors, the history of Sesamstraat, and all sorts of trivia about the show, complete with photos. It also contains a list of celebrity guests from the 25th season. "Poehéé!" is Tommie's trademark exclamation.
