New Adventures of Mary-Kate & Ashley #31: The Case of the Giggling Ghost: (The Case of the Giggling Ghost)

Mary-Kate and Ashley are excited to attend their town's annual Halloween Carnival. Every year, the carnival's proceeds go to charity -- but this year, few people are riding the rides or playing the games. That's because there's a ghost at the carnival that's scaring all the kids away!

The girls must figure out who or what the spectre is -- and how to get rid of it -- or the carnival doesn’t stand a ghost of a chance!
