Font Found in Empty ClassroomDecember 6, 2017

I had to snap this photo when I went into an empty classroom and saw these marks on the blackboard. At the time I thought, “Hmmm interesting marks – it might be a good basis for a font. ” and I snapped the photo thinking that I might turn it into a font. The more I looked at the marks – the more I saw – it already IS a font. Can you read it? (Clue the last word is rabbit).
