Leo's parents have just returned from Egypt, bringing back serious sunburns and an authentic sarcophagus of a cat, which the ever deft Mot manages to crush immediately. Cutting short Leo's rage, the monster swiftly sets off for ancient Egypt, the only place where one can find an identical cat sarcophagus, ferocious guards, mourners wailing like Tyroleans, a psychopathic High Priest and a neurasthenic Pharaoh. The difficulty here is not so much finding the way through the labyrinthine corridors of the pyramid, but rather trying to raise a laugh from the Ruler of Egypt, whose life is nothing but a vale of tedium.
