To Sleep with Wombats - When a visiting friend of Karla's (Keisha the wombat) turns out to be a night owl, Karla, Bo and Max are exhausted trying to keep up. They're convinced Keisha doesn't sleep! Mama shows them that all animals need sleep to survive and when she finds out that Keisha is a nocturnal wombat, she shows them how some animals sleep during the day. All Creatures Great and Small - After Max gets stuck between two trees during a game of Follow-The-Leader, he is mildly teased about being "big and round" by Bo. Max's feelings get hurt. Mama decides it's time to show some movies about how - and why - animals come in all different shapes and sizes.
