Scooby, Dancing Man and others in “Unfinished Business”

Ohh!

Scooby-Doo, your time has come. She is here.

Nova?

I am not Nova. I've only borrowed her body so that I may bring you an urgent message. Scooby-Doo, your life is in danger.

Huh?

I am of the Anunnaki, interdimensional beings that visit the planet earth every few thousand years. We arrive at a time call Nibiru, when the barriers between our worlds grow weak. The Anunnaki have a great history of helping humans, but we have no physical form and must inhabit animals. This is why some animals, our descendants, can talk and others cannot. But not all Anunnaki are kind and good. There are evil ones. And the most evil one of all is imprisoned beneath Crystal Cove and must not be set free. You must undo it, Scooby-Doo. Undo it all. Save yourself. Save your friends. Save the world.

Hmm? Hmm? Duh! The cursed treasure is evil. Evil! We have to destroy it!
