Yesh, I love A Christmas Carol and Charles Dickens. The ghost of Christmas past (Jimmy), present (SpongeBob), and future (Timmy) decide it's time to teach Danny a thing or two about Christmas. I know this may sound confusing, but the three ghosts are NOT the real Jimmy, SpongeBob, and Timmy. They just look like them because Danny's used to seeing them a lot. The real Jimmy, SpongeBob, and Timmy are in the story, though. They play the other people Danny hasn't been very nice to since the Christmas season started.
