The Great Vampire Robbery

This is a silly comedy about a fantasy world in which humans are believed to have gone extinct and magical creatures have inherited power in their absence.
How do we know that humans aren't REALLY extinct? Because the Gorgon President has just caught a blood-drinking vampire on safari! And where there's vampires...
The Great Vampire Robbery deals with a troop of incompatible creatures- a shaman, a were-cow, troll and half-wizard to name a few, who seek to kidnap a vampire from the White House in order to find its cache of hidden humans to sell their lucrative blood at a premium.

But things don't always go as planned...
