About the AU
Spawning from fanart, this AU places the four (and other extra characters) as characters from The Shape of Water.

Since the Amphibian Man is based on the Gill-man from Creature from the Black Lagoon, as well as the 2017 film being a remake and its own version of it, fans like to consider this AU an alternative to Monster AU.

Princess Anna
For the Peanna pairing, fans cast Anna as Elisa Esposito.

Mr. Peabody
For the Peanna pairing, fans cast Peabody as a dog version of the Amphibian Man.
