It's stinky. It's noisy. It can be really funny. It's a fart! Most animals can fart, but some animals either don't or can't. While a fart might seem just like a stinky joke, farting and the ability to fart is an important part of an animal's complex digestive system! Through this gross-out book's exploration of farts and farting, readers discover why animals fart. This volume presents where farts come from through full-color illustrations exploring the digestive systems of animals, supporting science classroom learning as well as explaining a high-interest topic.
