Les Pyjamasques et le marchand de sable (English:
The Pajamasks and the sandman) is the ninth book of Les Pyjamasques which was published by Éditions Gallimard on March 25, 2010.
The sandman thought he had asleep the entire neighborhood when his path crosses that of three zigotos perfectly awake. But what are these three in the middle of the night? "Dorlidodo! Dorlidodo! It's time for you to go to bed, my little ones, "said the enchanter, blowing a handful of sand. "Ouch! How are you going? "Les Pyjamasques reply.
Sand, sheep, enchanted lullaby, the sandman tries everything in his power to put the imps to sleep, but nothing works.
It is noticed that the logo in the front cover of the book is changed slightly to have the silhouettes of the main character's eyes to look transparent. This change was kept until Les Pyjamasques et l'opération zéro.
There is one line in the book that makes a reference to the French equivalent of snake oil.
