Moonbeam is a Japanese dwarf flying squirrel. She lives in the mountain forests of Honshu, Shikoku and Kyushu, in Japan, and nowhere else on Earth. Her head and body are 14 to 20 centimeters (5.5 to 8 inches) long, about as long as a grown-up's hand. She weighs about 100 to 170 grams (3.5 to 6 ounces), about as much as a small apple. Her coat is smoky grey-brown with a white belly. Her eyes are very big and round, made for the dark. Her tail is flat and furry, about two-thirds as long as her body.
The power is the cape. A fold of furry skin runs along each side of her body, from wrist to ankle. When she leaps and spreads her legs, the skin catches the air, and she glides from tree to tree. She wakes shortly after sunset and rests in a tree hollow by day. Her bed is often cedar bark, split into fine strips. She eats buds, leaves, seeds and cones, and from winter to early spring her droppings show she eats cedar pollen. She does not sleep through winter. She keeps coming out into the cold night.
About as long as a grown-up's hand, and about as heavy as a small apple. She does not sleep through the winter.
