Tao's Adventure: Curse of the Demon Seal (TAO魔物の塔と魔法卵 Tao: Mamono no Tō to Mahō no Tamago, Tao: The Goblin's Tower and the Magical Egg) is a Nintendo DS video game developed by Konami.
The game revolves around a boy named Tao from the island of Bente, who must travel to Mondominio to get a rare monster egg from the monster tower. The seal from the tower has been broken, and monsters have turned all the people of his village into stone. Tao meets a creature named Petcho, who calls himself an "Elite Monster," and follows the main character throughout the game.
The game is a semi-sequel to Azure Dreams, which was released 8 years earlier.
