Koala Boy Kokki

Adventures of the Little Koala focused on the adventures of Roo Bear, and his family, who were Koalas, and his friends, Nick, Pamie (penguins), Floppy, Mimi (rabbits), Betty (koala), the bully Walter (kangaroo) and countless others. There was also an old character named Weather, who could forcast the weather, and his gliding friend Mingle, a young animal who was apparently an orphan. (Source: AniDB)
