I appreciated that this book had multiple story lines so as to keep the plot from getting dry. However, there seemed to be some continuity errors. In a previous book, I thought someone had taken away the Glass Cat's vanity so that she stopped repeatedly saying "I've got pink brains and you can seem 'em work!" - yet in this book that phrase is said often. Also, near the end, Professor H.M. Wogglebug, T.E. is talking about his invention of the Square-Meal Tablets as if this is the first time we've heard of them, which it's not. Also I felt like Ruggedo and Kiki were very easily conquered even though they were the main antagonist of the story.
