Les Pyjamasques et la momie d’Apophis, Tome I (English: The Pajamasks and the Mummy of Apophis, Volume I) is the twenty fourth book of Les Pyjamasques which was published by Éditions Gallimard on October 18, 2018.
At the museum, the Pyjamasques discover ancient Egypt. They are fascinated by the mummy of the giant snake Apophis, who wishes that the night be eternal, and, for this purpose, turns the boat of the sun from its path. In the evening, the Pyjamasques return to the museum in search of this famous boat. Suddenly a laugh sounds: the mummy of Apophis comes out of his sarcophagus! Our heroes are divided between the temptation of an eternal night and their duty to fight Apophis.
