This is the first in the series I've read. It's funny, engaging, well illustrated and easily holds the reader's interest. Each princess and their pet has a secret super hero alter persona. As the cloud of stink gets pushed away from each kingdom, another superhero pair gets involved, but nobody seems to be able to figure out where the stench came from, or how to get rid of it. Ultimately, those living in the place where it originated become just as nauseated, precipitating a crisis that leads to a successful solution. As I was reading the story, I couldn't help but think this could also work as a bedtime story to get stubborn kids into the bathtub.
