關(guān)卡描述(游戲中)：

Level from 'Lost Time'. This is the second level out of all twelve.

As the planets explored deeper into the cave, they found that they were unable to keep going due to strong magnetic fields; however Ice Planet was able to see a stone pillar with three gems missing because of the cave-in.

They went back to the surface and had to revisit Neo Cosmos to seek help from Sef. Sef lent them the power of the third planet right away. Not only that, he also told them that they had to find the owner of the three missing gems to regain power in order to reactivate the cogwheel and save the world.

To do this, they first needed to improve their skills of third-planet movements, and Sef's test began.
