The creators of Brains On!, the award-winning science podcast for kids, introduce readers to a fact-filled and humorous look at the weird and wonderful world of microbes!

It's show-and-tell day, and Dominique can't wait to introduce her awesome pets to the class. They're more helpful than dogs, cuddlier than gerbils, and way smarter than lizards. They're her…MICRO-PETS!
 
As Dominique takes her classmates on a tour through her microbiome, they'll meet some face mites, hang with feet fungi, and visit the fart factory—powered by bacteria in her intestines!
