I believe that the theme of "The Bat-Poet" is that C. being different from others need not prevent one from finding happiness and satisfaction. The bat-poet was very different from the rest of his family, and the entire species, by wanting to create poetry and become a celebrated poet. Although there were many difficulties throughout his artistic life, he nevertheless managed to become happy and satisfied, despite what everyone else thought about him.
