This level is quite different from the others. First of all, it is set underwater. The moves you can perform are basically the same, only here you can jump much higher, as if the force of gravity were lower. It is also the only level where you can use the "dive" skill, which you can get in the third basketball court. Also, in this level you will not have to face any bosses and you will not get any pieces of the time machine. In practice, it only serves as a link to reach the oriental village. In fact, you should face it only if you have already completed all the previous levels, otherwise you will be forced to go through it later, backwards.
Immediately after the start you will encounter a catfish, which will come towards you at great speed. Eliminate it promptly with the club. In the barrel you will find a bronto burger. Another catfish will be swimming above you, wait for it to pass before overcoming the abyss on the right. Here you will find a cactus cooler. Climb higher and eliminate the jellyfish you encounter. There is a barrel with a heart inside at the end. Now you will have to overcome a long line of suspended platforms, on which algae-like enemies move. You will therefore have to be careful not to get hit by these algae or catfish you will encounter, or you will fall down. Before you jump, make sure you can land safely on the next platform by timing it right. The algae are very leathery and it takes a lot of hits to kill them, unless you charge a powerful attack. Be careful during the last jump, you will have to eliminate a crustacean that will come towards you, at the top. Continue to the right and take advantage of the rising bubbles to overcome the next abyss. Kill the jellyfish and pull yourself higher. Then carefully go down the hole on the right. In the barrel on the ledge on the left there is a heart.
Now there is the tricky part of this level. You will have to go through a floorless passage, where there are two rows of bubbles moving horizontally, to the left. To continue, you will have to jump on these bubbles, obviously avoiding falling to the bottom. You cannot hang to the bubbles, so you have to jump with precision. If you can, always stay on the top row of bubbles. You will also encounter a shark along the way, but that shouldn't bother you. To get through this area safely, the diving skill you should have obtained will be very useful. If you fall, quickly call Gazoo and sacrifice some coins. Once on the other side, continue to the right. You will get a cactus cooler and a bronto burger by breaking the barrels. Jump over the abyss, grab the next ledge and pull yourself up. When you get to another gap, drop down, moving to the right. In one recess are two barrels, containing a heart and boomasaurus eggs. Then go back to where you were before and this time jump to the top right. When you grab onto the ledge though, wait a moment before pulling yourself up! A shark will pass right over your position and if you pull yourself too up early it will hit you and inevitably plummet you. So wait until it has passed. Then kill the next shark if you want and reach the wall on the right. Grab the ledge above and pull yourself up to exit the lake.
