Turn right and pull yourself up onto the monkey bars. Kill the mummy and crush the chest to get the red crystal. Then jump on the platforms on the left to cross the quicksand and reach the well. Instead of entering it, however, go around it, to find a silver key behind it. Go back, jumping on the platforms and collecting the crystals under the monkey bars. Use the moving platforms to reach the cage, open it and press the button. You will then be able to reach the suspended crate where you started the level. Inside, you will find the first Gobbo. Then go back to the well and jump into it.
This area is dark and finding your way around is not easy. Look around until you see a row of crystals under some monkey bars. Grab the monkey bars and collect the crystals. Continue along the path, jumping on the elastic platform, until you reach a chest containing the second Gobbo. Once you get it, go back to the well you came out of and go to the other side. Keep following the path, jumping on the elastic platforms and collapsing platforms, until you reach another well. Don't go inside, though. Climb on the crates to the right. You can reach an extra life and the blue crystal. After getting them, crush the two crates and the Red Dantini that is below. You will get some crystals and the third Gobbo. Go back to the well and this time go left. You will have to overcome a tornado, which appears intermittently. So move with timing. Jump on the collapsing platforms to reach another well. Enter it.
Move the movable crate to be able to reach the platforms moving in a circle above the quicksand. From these platforms, you can reach a suspended chest with a silver key on it. The crate contains crystals. Climb back onto the moving platforms to free the fourth caged Gobbo with the key you took. Then there are two other chests that you can reach: one of them contains the green crystal and the other common crystals. After taking everything, enter the well you entered and go back the way, until you return to the well that you ignored earlier. Enter it.
You will find yourself underwater. Follow this simple path, avoiding electric shocks. One of the crystals you will find is the camouflaged pink crystal. There is also a chest containing other crystals. Watch out for the enemy at the end, who will shoot you when you get close. Kill it and behind it you will find a silver key. Take it and exit the tunnel.
Kill the hammerhead fish and open the cage to get the fifth Gobbo. Quickly eliminate the Dantini with the harpoon that shoots you, below and break the two crates to get more crystals. Then enter the duct, before the Dantini reappears.
This area is even darker than the one you passed through previously. To illuminate the area around you, you will need to take the bright jars that you will find. You will have to be quick though, as their effect is temporary. There is an extra life near the well you came out of. After you get it, take the light jar and quickly follow the path. Basically, you will have to cross quicksand by jumping on platforms. You will reach another jar. A little further on, there are platforms that move in a circle, with another glowing jar in the center. Take it only when the one you already have has run out. On the platforms on the sides you will find another extra life and the camouflaged yellow crystal. Then enter the crystal door at the bottom.
As in the previous level, you will have to compete in the race with the ghost. Here, however, there are no strategies to win easily. At the beginning, immediately turn right. The path is not difficult to follow, but compared to the previous level there are more platforms that collapse and at a certain point, you will have to jump onto a very thin column. Try not to get all the crystals, so as to slow down the ghost. Eventually, you'll have to jump across three collapsing platforms, one after the other. You will notice that to the right of the one in the middle there is another platform: ignore it and go straight, to reach the silver key, in front of the gong. After grabbing it, go back and head in that direction instead, to free the caged Gobbo. Go back to the gong and hit it to complete the level.
