When Darren Stonkadopolis and the rest of the Fart Squad were bussed off to the Natural History Museum, they had no idea that a couple of gulps of root beer could mean the end of Buttzville.

But when Darren melts a petrified tar pit with a volcano-hot fart, he lets out what the pit had been holding in—the deadliest farter in all history, the ferocious Fartasaurus Rex. Now it's up to the Fart Squad to chow down, power up, and blast this prehistoric beast back to the Flatulent Age before the whole town becomes fossil fuel!
