Miss Koala is a major character in the special Back to School with Franklin. She is a replacement teacher who came riding up on her motorbike and filled in for Mr. Owl beginning on the first day of first grade, as Mr. Owl had to leave due to a family emergency. 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 and takes away his pencil box puppet for a while because he was goofing off. However, 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 and a black vest. She creates a soccer team consisting of Franklin's entire class and has them play against another class she once taught. Everyone is sad to see her leave when it is announced that Mr. Owl will be back. She, however, reminds them that she is only a replacement teacher and helps to cheer them up by suggesting they draw a picture to welcome back Mr. Owl.
She is voiced by Carolyn Scott.
