In many platform games there is at least one level with icy and slippery surfaces. This is the case with the sixth cavern in this game. In fact, there are many frozen floors, on which you could slide at great speed, risking, however, to end up in the precipices or to hurt yourself by hitting the walls. However, the main pitfall of this cave is not the ice, but the spinning sticks with spikes that can hurt you a lot if you run into them. At the beginning of the level, slide to the right. Jump over the gap and land on the highest ledge. There are two piles of stones hidden in the ceiling in this area. Then go back and take the lower passage. You might find a diamond here, but to get it, you'll need to get past one of those spinning sticks described above. The only way to pass it safely is to hit it with stones to make it gradually sink, but it will take many of them. You decide whether to do it to get the diamond or not.
Go left and drop into the small depression. Swipe to the left. You will find stones in the ceiling further ahead. Then dig the loose soil beneath you and let yourself fall. Also in the space below you you may find a diamond, to reach which however you will have to pass a spinning thorny stick. Do it if you want. Go right and go past the two columns by digging under them. You will find other stones in the ceiling. Dig the loose soil below you and take the passage to the right of the column below. Go down the steps to the right. Crawl into the narrow tunnel on the left and knock down the spinning stick you find with the stones. Behind you will find numerous stones and a mushroom in the ceiling. Go back and crawl into the tunnel on the right. Climb up, digging through the loose soil and you'll find a diamond. Keep going up and plummet the two pink rocks to clear your way. Proceed to the left to go back to where you were before and this time go down to the left of the column. Sliding across the ice to the left, you will arrive above the pillar to press.
After pressing it, dig the loose soil below you and continue to the left until you exit the tunnel. You may find another diamond protected by a spinning stick above you, but don't waste your time. Glide along the ice on the left and be ready to take a long leap to cross the gap. Be careful not to get hurt by hitting the wall and crawl into the small tunnel. Then go down the path on the left (you won't get hurt thanks to the inclined planes) and proceed to the right. Above you, you'll notice a flying dragon spitting fireballs. Ignore it and pass under it, sliding on the frozen surface. When a thorny stick pops out of the ground in front of you, jump over it. Shortly after, however, another will appear, which you will not be able to pass. You will then have to stop first and make it sink into the ground with the stones. Take the passage on the right where the exit door is, but before reaching it you will have to sink another thorny stick with the stones.
If you were quick enough, you should have reached the door before time runs out. In case the door has already closed, continue to the right. You will have to knock down another thorny stick with the stones, behind you you may find a diamond. Then touch the wall on the right and you will be teleported just above the pillar. Proceed to the right, go down and go left to press the pillar and try again.
