Lenny, the littlest koala bear, doesn't want to walk home without his big sister, Kit. Much to his dismay, he begins the long trek through the forest on his own. Along the way, he encounters a sloth swimming in the river which Lenny must cross in order to get home. He thinks the sloth will be able to help. Then his sister Kit shows up beside him, and Lenny has to make a decision. Should he take a chance and go with the sloth or go home with his sister? What would you do?
