This area is also very large, and you have no Turtle Van to help. You will mostly navigate the underground passages. Above the skies in the overworld fly some bombers that will try to bomb you. They are easy to avoid. In the levels, you will occasionally find a few hazards you've never seen before: spikes, fire (instant death), and walls that will try to crush you (also instant death).

The easiest road to take is 1 - 2 - 3 - 6 - 8 - 9 - 12 - 15- 17 into 18. There are paths to choose from and even 2 dead ends (which acts as a refill station with pizza) Careful manuvering on the treadmills. Spikes are a steady drain on your health and the laser security systems suck but can be beat by any turtle in one shot.

Your captured turtle is in 13, thats all thats there. Backtrack out and go to passage 12 to continue. You can keep going forward if you want but passageway 14 is tough with the hardest jump in the game. (Missing it knocks your turtle into one of three firepits in the game and cooks your turtle (IE he's dead Jim) and your turtle won't respawn in 13 if you already rescued a turtle. 15 has a fire jump to, but it's not nearly as tough. 14's has a lower ceiling on a conveyer with a bug that will hit you if you don't advance far enough. ANOTHER WARNING ABOUT 14, it has magnets which WILL Pull your turtle, so if you change your mind, DON'T GET OFF THE LADDER, if you do, you commit to this passageway!! Magnets appear in other parts of this stage, but in none of the passages I listed above for the easiest road to take.

You cannot backtrack out of 15 without losing a turtle as the security system will hit you on your jump across the firepit and knock you in. If you have triple throwing stars, you MAY be able to hit it.

Passage 17 has one block drop down platforms going past moving spike walls which can also instantly kill you. YOU HAVE NO MARGIN FOR ERROR HERE. As soon as you aproach the drop STOP PUSHING FORWARD and let your turtle drop. DO NOT GO FOR THE WHOLE PIZZA, you are dumb if you do, it cannot be reached.

BOSS is a Giant Mouser, stand underneath with Don and swing upword over and over when it opens his mouth. Wow, you can almost sleep during this fight. Easiest part of the game.
