Sgrìobag is a monster who lives in a plain white world, but with the help of her pencils and paper it does not stay white for long. Sgrìobag draws a frog called Lachaidh who remembers having a spell put on him, but cannot remember what he used to be before he became a frog. Sgrìobag suggests they look for clues by the pond. They soon meet a princess and follow her to the palace, where they find out they are just in time for a fancy dress party - but what costume should Freddie wear?
