It's the third adventure from the bloaters of the big leagues， the stinkers to the stars， the gassians of the galaxy . . . the fearless FART SQUAD! This laugh-out-loud chapter book series is perfect for Captain Underpants fans. With black-and-white illustrations throughout and porta-potties full of bathroom humor， young readers will be giggling from start to finish. When Darren Stonkadopolis claims he's had a close encounter of the stinky kind， the other Fart Squad members think he's full of hot air. But then the alien Stink Weeds descend， and the Fart Squad is forced to smell the truth. It'll take some Weedwacking， stealthy stench tactics， and buttfuls of gas so smelly they'd make the sun blush to stop these mutant extraterrestrial vegetables from universal stinkination.
