The "Tale of Tales" is a very famous, moderately deranged collection of folklore from 16th century Italy. It's by the author Giambattista Basile, a storyteller who traveled the Mediterranean region collecting stories. The collection known as "Tale of Tales" follows a similar framing narrative to "1001 Nights", with the storyteller telling the king stories in a very loosely-connected fashion.
I'm not even going to say the titles for today's stories, but they are two of the most famous in the collection and wildly unpredictable. They're gross, violent, weird, and interesting - so, basically like everyday life.
The creature is a man...who is a bat. But he's not Batman, because Batman can't handle this little guy's intensity.
