Les Pyjamasques et Roméo Mécano (English: The PJ Masks and Mechanic Romeo) is the third book of Les Pyjamasques which was published by Éditions Gallimard on October 26, 2007.
The night is beautiful. Les Pyjamasques and their friend Ptigarou dream in the moonlight, when emerges in the distance a disturbing machine. In the cockpit, a little not very wise boy wavers in the middle of levers and screens. It's Roméo. Inventor of strange machines, he decided to capture the moon to cut it into pieces and sell it to the cheese shelf of the supermarket!
