They sound like bad guys, they look like bad guys ... and they even smell like bad guys. But Mr. Wolf, Mr. Piranha, Mr. Snake, and Mr. Shark are tired of being the villains. Mr. Wolf has a daring plan for the Bad Guys' first good mission. They are going to break two hundred dogs out of the Maximum Security City Dog Pound. Will Operation Dog Pound go smoothly? Will the Bad Guys become the Good Guys? And will Mr. Snake please stop swallowing Mr. Piranha?!

A crackerjack criminal crew of animal outlaws are about to attempt their most challenging con yet: becoming model citizens. Never have there been five friends as infamous as these guys: dashing pickpocket Mr. Wolf, seen-it-all safecracker Mr. Snake, chill master of disguise Mr. Shark, short-fused 'muscle' Mr. Piranha, and sharp-tongued expert hacker Ms. Tarantula, aka 'Webs.' But when, after years of countless heists and being the world's most-wanted villains, the gang is finally caught, Mr. Wolf brokers a deal to save them all from prison: they will go good. Under the tutelage of their mentor Professor Marmalade, an arrogant (but adorable!) guinea pig, they set out to fool the world that they've been transformed. Along the way, though, Mr. Wolf begins to suspect that doing good for real may give him what he's always secretly longed for: acceptance. So, when a new villain threatens the city, can Mr. Wolf persuade the rest of the gang to become the Good Guys?

When Dr. Marmalade prepares to destroy the world, the Bad Guys have a chance to be superheroes.

"OK. A lot of the stuff we said on the back of the last book was NOT TRUE. We now admit that The Bad Guys is WEIRD. We also admit that it features ALL the weird stuff we said it didn't. PLUS there's now a whole bunch of even weirder stuff involving an over-sharing bat, a really scary new character who lives in the woods, and a strangely confident little guy with a mullet. So, uh, don't relax, maybe FREAK OUT a little and have your MIND BLOWN by the BAD GUYS!"--

Still yearning to be seen as heroes, Wolf, Shark, Snake, and Piranha set out to rescue ten thousand chickens from a high-tech cage farm--but one unexpected problem is Mr. Snake himself, also known as "The Chicken Swallower."

"They may look like Bad Guys, but these wannabe heroes are doing good deeds... whether you like it or not! Discover all you need to know about the baddest guys around in this all-new novel based on the major motion picture!" --

Snake's terrible powers are revealed while Agent Fox suddenly has a whole lot more backstory than expected.

"The bad news? The world is ending. The good news? The Bad Guys are back to save it! Sure, they might have to "borrow" a rocket. And there might be something nasty in one of the spacesuits. And Mr. Piranha miiiiight have eaten too many bean burritos. Surviving this mission may only be one small step for man, but it's one giant leap for the Bad Guys"--Page 4 of cover.
