Crystal Cove is the main setting of Scooby-Doo! Mystery Incorporated. It is a fictional, coastal town in California originally founded by Spanish conquistadors. These conquistadors brought with them a crystal sarcophagus containing a cosmic, interdimensional evil. They buried it deep underneath the area; subsequently, Crystal Cove became a hub of strange activity - such as criminals dressing up as monsters - as a result of this entity's influence.
