You can still get Vampire dragons, but you must catch them on the Abandoned Page or have a friend bite an egg and gift it to you. I have heard rumors of cave born vamps, but have yet to see one.
Edit: (Serin-no-Kaze)
Cave Born Vampires come from any Vampiric Dragon biting a Caveborn egg. As long as the egg is caveborn, the vampire will be.
~ Vampire dragons can only be obtained by hatching a vampire egg, which is done by either
A: Getting an egg from a friend and hatching it.
B: Snatching an egg off the Abandoned Eggs page.
C: Having one of your own Vampire dragons bite an egg, and hatch that one.
To get a cave born vampire, you had to catch one on Halloween of '08 and hatch one of those. Any other vamps were eggs bitten by other vampire dragons. All you need to do is get an egg that used to be cave-born before being bitten.
Of course, there's only a 50% chance it will succeed. 1 quarter of the time it will die, and the other wuarter of the time it will become a vampire egg, but the other dragons will be disgusted by it and throw it onto the AP.
These are NOT zombie or neglected dragons, which are entirely different species.

If you mean the friend area called Dragon Cave, these are the Pokemon that will live there when recruited: Bagon, Shelgon, and Salamence.

You can't get eaten by a sea dragon in Hazy Maze Cave. Nintendo just want to scare kids by putting the warning sign in the cave.
On Dragon Cave, you can not 'create' dragons. These dragons are found on the main page, either in the abandoned section or on the bottom of the page. Then they are either eggs or hatchlings, and if they get enough unique views, become adult dragons.
