Miss Koala is a (former) main protagonist of replacement teacher who filled in for Mr. Owl beginning on the first day of first grade in the special Back to School with Franklin. Mr. Owl had to leave due to a family emergency and so she came riding up on her motorbike. She has a vibrant personality and loves trying new things and doing things a different way. At first, Franklin doesn't like her, especially when she makes him give up his favorite seat next to Bear for a while because he was goofing off. After he learns more about her, such as that she's from Australia and learns to understand her Australian sayings such as "good on ya'" and "fair dinkum," he warms up to her. She wears a purple bandana around her neck. She creates a soccer team consisting of Franklin's entire class and has them play against another class she once taught. She is voiced by Carolyn Scott.
