After defeating Dracula , Donald receives a more complete map . In India , Donald enters the palace of the Maharajah , where she challenges him to defeat the tiger in her garden in exchange for a Sphinx Tear . Donald succeeds and receives the Sphinx Tear , which is the key to open a temple in Egypt . Donald is able to solve the " Riddle of the Sphinx " using the note Goofy had given him , and obtains the Scepter of Ra before escaping in a mine cart . From there , he journeys to the South Pole , where he finds a key frozen in ice , and uses the Scepter of Ra to melt the ice and grab the key . The key unlocks the hold of a Viking ship , which contains an ancient diary with the secret to locating the treasure . The ship is haunted by ghosts , and the Viking captain sends Donald below decks to get rid of them . After defeating a skeletal Viking warrior , Donald returns to the deck , where the captain informs him that the diary is hidden in ice near the South Pole , and gives him an " ancient Viking plunger " that attaches to flying creatures . Donald then returns to the South Pole , hitching a ride on one of Pete 's bird minions to reach the diary .
