Evil megalomaniac, Obsidian Stone, brings the mummified Egyptian Prince, Nakthi, back to life so he can damn the Nile with upside down pyramids and thereby prove he is the most powerful man on Earth. But he is as short-sighted as he is greedy. He doesn’t count on the pesky Skinners tricking him, by dressing Henry as the mummy, and foiling his megalomaniacal scheme. Will they pull this off… or will they get trapped inside the pyramid in the process? Theme: It's not your clothes but your actions that count.
