|The Moon Stones|
Each Moonstone is a transparent object, with an encrusted symbol, or a liquid object. There are seven Moonstones, all of which are different colors. Lord Vampyre's Moonstone is encrusted with a bat, for example, and the Crazy Scientist's Moonstone is holding inside lightning strikes.
In every corner of the Monster Realms, there are hidden Moonstones, 7, in total. They are guarded by the monsters in the Realms, and are always well protected. Each Moonstone possesses a magical power. For example, Lord Vampyre's possesses the power to control people, and turn them into his minions, and the Mummy's has the power to magnify the curses. The only Moonstone that Lord Vampyre doesn't possess in the Castle is the Zombie Moonstone, most likely due to its later release. If one possesses six Moonstones, they will open the gateway to the darkness and eclipse the sun forever, turning day into night, and letting the monsters roam freely. The only Moonstone to possess two powers is that of the Crazy Scientist, which possesses the power to create life through the power of lightning and grant enormous strength.
