The theme found in both stories is the concept of unexpected outcomes or the idea that things are not always as they seem. In "The Moss from Chimera's Cave," the moss appears to be worthless and unremarkable until it is revealed to have healing properties. In "The Fool, Who Fished for a King," the fool's seemingly simple fishing trip turns out to have significant implications for the kingdom. Both stories highlight the idea that appearances can be deceiving and that there is often more than meets the eye to a situation.
