The blue jewel on Nabooti Island in the game Poptropica is inside the sphinx. Inside the sphinx you must solve a series of block puzzles that will lead you to a room with two statues. Farther into the room, you will find containers that have dots on them and corresponding levers. Click on the levers in order of how many dots the containers have, starting with one dot, then two, and so on moving quickly to avoid a sand flood. After clicking on the fourth lever, the blue jewel will be revealed in the mummy case.
