When Jenny Wren learns that Peter Rabbit would like to know more about the four-footed friends who share the Green Meadows and Green Forest with him, she encourages him to speak with Old Mother Nature who is only too happy to help. During their "classroom" chats, she not only teaches Peter about Arctic Hare and Antelope Jack but also tells him about such creatures as Flying Squirrel, Mountain Beaver, Pocket Gopher, Grasshopper Mouse, Silvery Bat, Mule Deer, and Grizzly Bear.
