Hint: 100%:
In order to get 100% at the game select menu you have to find a secret lums in the Tomb of the Ancients level. In the first part of the level, after having activated the 3 switches that raise the platforms in the poisonous pond, jump on these floating platforms and climb the web on the other side. Once at the top, instead of just falling down the pit, place yourself at the edge of the wall, to the left (when facing the poisonous pond), Then, fly over the pond, go as far to the left as possible to find a narrow hall in the wall, and land on the platform. Follow this path and kill some pirates to get the 1000th lums in the skull's eye.

Hint: Ride the walking shell:

On the level with the giant machine chicken, notice the four Lums under the stones that you cannot get. After you free four of Globox's kids, return to the chicken. When you are on the shell, press B repeatedly to move fast. Go right by the chicken and it will start chasing you. When it steps on a stone, it will break. Then, go back and get the Lum. This will take a long time to complete.
