The central character is surely the sad frog. However, depending on the nature of the story, there could be other important characters. For instance, if the story is about the frog losing its habitat, there could be humans who are the cause of this destruction as secondary characters. Or if the frog is sad because of a lack of a mate, there could be other frogs in the story that are potential mates but reject the sad frog for some reason. So, while the sad frog is the main focus, other characters can play important roles in the story.
