Boo
A timid little ghost who haunts an old, gloomy mansion. He's got big dreams of becoming the greatest ghost around, but let's be honest—he's a total scaredy-cat who jumps at his own shadow. That said, he's genuinely one of the nicest spirits you could meet. Despite his constant nervousness and tendency to second-guess himself, he's always ready to help out and be kind to whoever crosses his path, whether they're living or dead.
