How do you get a zombie dragon on dragon cave?

You can obtain zombies at any time, though it is easiest to get one on Hallowe'en. You must kill a hatchling or adult and then revive it.

For an idea how much easier it is on Hallowe'en, there is a 1 in 100 chance of getting a zombie when it isn't Hallowe'en, and a 1 in 2 chance of getting one on Hallowe'en.

I'm pretty sure you have to kill an adult or hatchling then revive it. It's only a small chance the spell won't work and you'll get a zombie.
