Teenage Mutant Ninja Turtles/Area 2

This area has only two stages and you must go through both of them in order. Bombs have been set up in order to destroy the dam. You must get into the water and disarm the bombs, but to get to the water you have to go through the dam up to the rooftop.

Inside the dam
This level, while not as short as the previous ones, is still relatively short. The dam has only three stories. You will encounter a few minibosses on the way (NES only). To the far right of the third story is a full pizza, though you must fight a miniboss to get it (miniboss on NES only). After you exit the level, walk to the right until you encounter a break in the railing and take the plunge into the water.

In the water
You need to find all of the bombs within 2 minutes and 20 seconds to complete this section. It is known as one of the most difficult sections in a NES game. In addition, letting the time run out is an instant Game Over (you can still use a Continue), so if you failed to reach it on time, you are best to let a Turtle die instead to reset the time.

April will tell you how many bombs remain by pressing.

Upon starting the level, you will immediately encounter a bomb to the right. Be careful not to get hit by the electricity on the way. As you proceed to the right you will encounter coral-like spikes. These will automatically kill you if you get too close. In order to get all of the bombs in time you may have to swim through electricity to save time, however, it is easy to lose all of your life on this level so be overly cautious.

Here is the quick guide to beat it without backtracks:
 * Bomb 1: First bomb on the right.
 * Bomb 2: On the split path, go up.
 * Bomb 3: After Bomb 2, go back down. Then, go to the right path.
 * Bomb 4: Continue going to the right, then go up. The bomb is to your left.
 * Bomb 5: Go deeply to the right before going up.
 * Bomb 6: Go up and be very careful on the electrical reefs. Continue going all the way to the right.
 * Bomb 7: Go down. It should be on the right side.
 * Bomb 8: Go down. Blitz through the obstacles. Be careful not to go too low to the coral-like spikes.
