The plot of Croaki Croaki Literature Club, is that Onee-san Inc. (Aka Steve McKoy 11), was inspired by Doki Doki Literature Club, a game by Team Salvato. DDLC (Doki Doki Literature Club), is a long 2017 psychological anime horror game, and Onee-san Inc., was inspired by the game that he decided to make a short, educational amphibian version of DDLC, called "Croaki Croaki Literature Club" for his class, because it talks about information about frogs and other amphibians (Released on June of 2020). This game he made was short, so there was no horror or disturbing detail with it, it was the same way as the starting when the protagonist joins the literature club. There are a few characters, which is Salyori, Frogika, Newtsuki, and Toad. (If you want to learn about the characters, it's right here: A Main Character.) The game came out successful. It's made with Ren'Py, and put on itch.io too.
