This is funny, but incomplete. Unlike the previous two books in the series, this one doesn't really have a full plot. A new character is introduced, the villain escapes, and the Bad Guys have another new problem to deal with.
The funny touches are all there, complete with snark and bathroom humour. But this book feels kind of rushed and light on plot, at least compared to the previous installments.
Luckily, I've already got the next book, The Bad Guys in Attack of the Zittens, so I can keep reading and find out if this story arc gets resolved.
