The book contains stories about Tommie, Ieniemienie and Pino (complete with color photos), followed by educational 'bulletins' for children about all sorts of subjects. There are also a handful of comics about Dikkie Dik (a cat) and Janneke (a boy who can turn into different animals), and a few songs with sheet music.
All the material from this book was taken from a series of season-based Sesamstraat books about Spring, Summer, Autumn and Winter. Each book featured seven stories: one for each day of the week.
The book contains photos of the classic puppets from 1980, which have changed a lot through the years. Tommie still looks like a teddy bear, and Pino looks like a baby chick. Ieniemienie was recently added to the cast; her name was spelled Ienie Mienie during her first appearances.
The stories were written by head writer Ton Hasebos. Gerard Kuster, who played Gerard on the show, made little drawings of two characters named Kobus and Sanna. They appear all over the book.
Another Sesamstraat activity book, Het boek van Ienie Mienie en haar vriendjes, was released around the same time.
