From the Super Mario Wiki
Pokey is a character in Mario Party Advance. He is found lurking in a patch of desert. Once he encounters the player, he introduces himself as the guardian of the desert, and says that unless they answer his "Riddles of Mystery", they will be forever trapped with him. In exchange, he will grant them their freedom and a Gaddget. After all three of his questions are correctly answered, he says that he's impressed and lauds the player as a master of the desert's riddles. He sticks true to his word and gives the Tap-Tap Sumo Gaddget, and tells the player to continue journeying.
