Instead of a monster, could I have a look at what the AI you're using does when I give it the Corvus prompt?
A four-foor tall anthropomorphic raven with red eyes, wearing a black top hat with a red band and a purple crystal on the front. On his beak, he wears a red pince-nez (You know, those armless sunglasses Morpheus wears in the matrix?), and he wears a rat skull necklace around his neck.
In my experience, no AI out there has been able to do it correctly, so I won't be upset if it gets it wrong.
