Diary of a Mad Mummy is the tenth book in the Give Yourself Goosebumps gamebook series. It is preceded by The Knight in Screaming Armor and followed by Deep in the Jungle of Doom. The cover illustration shows a mummy standing next to a wooden table, with green liquid, books, and scientific equipment on it. The mummy is looking away from his diary, when he's writing in it with his left hand, and is holding a science tube, filled with the green liquid, in his right hand. The mummy is also wearing glasses and has gray hair sticking out from underneath his bandages at the top of his head.
