Stanley is a water monster that lives in a stretch of water just outside the Liverpool Avalon. The area is normally hidden from human view and several characters have been seen in Midform here.
Despite her name, Stanley is female as Lorne refers to her as 'girl'. She appears to be friendly with Lorne.
Stanley first appeared at the start of start of the exchanges arc 'handshakes' here with her second appearance some time later on page 22 of 'hello goodbye' here..
Stanley is about as sentient as a smart dog, and her species shows up in various lakes, rivers and loch's around the world.
It is possible Stanley is a Plesiosaur, as Kory has some interest in them.
