Castlevania/Stages 10 - 12

'The Fishmen return in force as you plunge to the underground depths of the castle. Bats will fly about at the least convenient moments while you ride platforms only inches above the water. When you rise to the surface, Hunchbacks will assail you as they drop from the claws of giant Eagles. And before you can face Frankenstein and his diminutive keeper Igor, you will be challenged by a slew of fire-breathing dragon skeletons.'

Stage 10
After descending to the underground tunnel of the castle where the Fishmen make their home, you will need to make use of the floating platforms that will ferry you over the deadly water below. With a continuous stream of Bats and Fishmen attacking you, you will have to chose the timing of your leaps very carefully.
 * Notes
 * 1) There is a Stop Watch located before the first platform.  While it may help you with some of the trickier obstacles in this leg, it won't be of any use against the boss.  Destroy a bat before jumping on to the platform.  Then stay low and whip any bats as soon as you see them coming so that they can't knock you off.
 * 2) The Holy Water found at the top of the ledge here is useful against Frankenstein, and can even be used against the dragon skeletons that you will face later.  Prepare to leap onto the next floating platform.  This time, you will have to crouch under the low-hanging ceiling, or you will be pushed off the platform and into the water below.
 * 3) After you crouch below the ceiling a second time, you are almost at the end of this challenging stage.  Continue to whip bats as soon as you see them, and don't pay a lot of attention to the candles above you unless you are sure you can whip them safely.

Stage 11
At first, you may think that this stage is void of enemies. Then a large Eagle will appear, clutching a Hunchback in its talons. It will drop the Hunchback off to fight with you. Then another will appear, and another, until the sky is full of Hunchback-carrying Eagles. And when it's finally over, you'll come face to face with a Dragon Skeleton.
 * Notes
 * 1) Once the Eagles begin to appear, they won't stop until you reach the end of the stage.  The Hunchbacks that they deliver may annoy you, but they will always drop to the ground precisely within striking range.  As soon as you see them fall, hold perfectly still and crack your whip a split second before they touch the ground.
 * 2) You will encounter your first Dragon Skeleton here.  Prepare yourself by standing at the farthest possible distance from it while still being within strike range.  Its head will writhe up and down on a long neck.  You can remain on the ground and wait for the head to drop low enough for you to strike it, or you can jump in the air to hit it as well.  Whatever you do, always be prepared to strike the fireballs that escape its maw.

Stage 12
This seemingly desolate sewer tunnel has exactly four occupants, and two of them are the guardian Frankenstein along with his handler Igor. The other two are Dragon Skeletons. Although these long necks with fangs can't approach you to harm you, they are difficult to kill and can do quite a bit of damage with their fireball attack. Don't underestimate them.
 * Notes
 * 1) The first Dragon Skeleton of the stage can be found here.  Stay on the higher ledge, and use the same strategy as before: Stand at the farthest possible whipping distance from the head.  Once you've destroyed it, don't forget to whip the block that it stemmed from in order to find the life restoring Pot Roast.
 * 2) A second Dragon Skeleton will appear here, in one last attempt to keep you from reaching the boss.  Don't get too anxious while fighting this beast.  Take your time, and whip at it as frequently as possible.  Don't let any of the fireballs slip past your whip either.  Break the block behind the dragon for a useful large heart.

The Pride of Frankenstein
Frankenstein and his little companion, Igor, are truly reanimated by your arrival in their hall. Although Frankenstein has certainly been bulking up, the real threat comes from Igor who leaps off Frank's shoulders and attacks you—but only if Frank manages to clear the platform over his head. If you've managed to hold on to the Holy Water all this time, you can use it to attack Frank and lock him in place, especially if you collect a Shot Multiplier. Otherwise, be prepared for a long fight, where you must constantly dodge Igor and the fireballs that he throws at you.
