Sneeze-O-Roma

Sneeze-O-Roma is a disease. It causes the victim to keep sneezing over and over again. As Hank puts it: "Those who get it, never FORget it, because you can't stop sneezing."

Victims
Both Hank and Drover have gotten this in the eighth book.

Causes
So far the only known cause is being whacked on the nose by a wooden spoon, as seen in the eighth book, when Sally May did this to Hank.
