Indeed, it is a new work from  mattmc95

His poor OC Charlie is an unlucky human scientist who got transformed into a massive alligator man. For quite a while, he has been living in the sewers, subsisting on mice and rats.

Roderick has been in the same boat, but he has had decades of getting used to being a giant crocodile. He feels a certain kinship with Charlie. He wants to show him that being a large reptile isn't the end of the world. And the best way to start the process is by giving Charlie a freshly cooked Beef Wellington. After years of rats, Charlie gets his first decent meal in a long time.
