Long teeth, brown fur, and a home made of logs and sticks--it must be a beaver! Or could it be a muskrat? In this title, young readers will learn how to spot the differences between the similar critters, from tails to size.
Fuzz, a possum who likes big excitement, convinces his friend Cork, a muskrat who prefers safer adventures, to go on a snowy exploration, which leads the friends into a situation that reveals the truth about their bravery.
When Cork and Fuzz agree to babysit a young porcupine, Cork ends up doing most of the work, and when Fuzz gets into some trouble, it is up to both Cork and the baby to come to his assistance.
As best friends Cork, a muskrat, and Fuzz, a possum, try to catch a mysterious floating yellow object, Fuzz eagerly keeps taking action while Cork cautions him to wait a moment first.
Although Cork the muskrat is short and likes to find things and Fuzz the possum is tall and likes to keep things, the pair remain best friends even after Fuzz finds Cork's lost stone and decides to keep it.
