Grab the balloon in front of you, which will lead you to a platform suspended above the precipice, on which there is a golden key. As soon as it is taken, immediately turn 180 ° and quickly go up the collapsing platforms without ever stopping, or the two Dark Dantini on the sides will hit you. Once back up, open the door in front of you and enter.
You will enter a dark area, full of quicksand. In the dim light, you will see rotating platforms. Jump on them, but hurry to kill the Dark Dantini in the center before it can hit you. Reach the islet with a single crystal, jump to the platform that leaps out of the quicksand and jump to other rotating platforms, quickly killing the Dark Dantini in the middle. Climb to another platform that leaps out of the quicksand, then follow the path, collecting the crystals. At the end you will find two chests, containing crystals and an extra life. Then jump to the next rotating platforms, once again eliminating the Dark Dantini in the middle. Finally you will come to a well: jump into it.
You will land in a completely dark area. Grab the light jar in front of you and get past the quicksand by jumping onto the collapsing platform while eliminating the Dark Dantini. Crush the crate on the other side to get some crystals and pass the quicksand further ahead, eliminating the Dark Dantini along the way. You will come to a point where there are two crates, next to a light jar. Break the crates first to get more crystals, then grab the jar. You will have to overcome other quicksand by jumping on rotating platforms. In the center is another bright jar. Two Dark Dantini will target you in the meantime, but you should ignore them. Reach the other side, break the chest to get some crystals and enter the door.
You will now have to go through an area very similar to another you have already seen. Reach the button and press it, to open the next well. In the meantime, you can get some crystals from two crates and you will have to eliminate two Dark Dantini. Then jump on the thin column, kill a third Dark Dantini, reach the well and jump inside.
Grab the crystals, then jump to the small platform and kill the Dark Dantini on the other side. Repeat the process and hold on to the monkey bars. You will have to go through them quickly, before the Dark Dantini reappears. Then use the jelly to jump over the monkey bars and get the extra life above them. Go back and follow the path to the next well. Enter it.
Another dark area, under a stormy sky. Take the long row of crystals and kill the Dark Dantini at the end. The path to follow is very linear. The only difficulty lies in the fact that you will have to avoid the attacks of the numerous Dark Dantines that you will encounter while jumping, and then kill them before they can attack you again. Along the way you will also find some other crystals. At the bottom, you will find the exit gong.
