Adventures of the Little Koala centered on the exploits of Roo Bear, his koala family, and his friends: Nick, Pamie (penguins), Floppy, Mimi (rabbits), Betty (koala), the bully Walter (kangaroo), and many others. The series also featured an older character named Weather, who could forecast the weather, and his gliding companion Mingle, a young animal who was apparently an orphan.
