Wild Kratts is an American-Canadian animated television series created by Chris and Martin Kratt. The Kratt Brothers Company and 9 Story Media Group produce the show, which is presented by PBS in the United States. The basic plot of each Wild Kratts episode is to save an animal or animals under threat, be it by villains (Zach Varmitech, Gaston Gourmand, Donita Donata & Dabio, and Paisley Paver & Rex), general human influence, or confusion on a baby animal's part. The show's aim is to educate children about biology, zoology, and ecology, and teach kids small ways to make big impacts. It has ties to the Kratts' previous shows, Kratts' Creatures and Zoboomafoo, and contains numerous characters from the latter.
