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!

In The Case of the Hiccupping Ears, people all over the world are forgetting how to eat, see, hear, smell, and even walk! What on earth is going on? The boys at B.A.D.D. (Bungling Agents Dedicated to Destruction) are once again at work. Only Secret Agent Dingledorf and Splat can stop them.

Only Secret Agent Dingledorf and his trusty dog, Splat, can find the answer. Only they can save the day while also learning the importance of obeying those in charge. This funny, zany story is an adventure about following rules and the chaos that happens when we don't! Book jacket.
