Alex Sparrow and the Really Big Stink

"Alex Sparrow is a super-agent in training. He is also a human lie-detector. Working with Jess - who can communicate with animals - they must find out why their friends, and enemies, are all changing into polite and well behaved pupils. And exactly who is behind it all. This is a humorous tale full of farts, jokes and superhero references. Oh, and a rather clever goldfish called Bob. In a world where kids' flaws and peculiarities are being erased out of existence, Alex and Jess must rely on what makes them different to save the day." (toppsta.com)
