This is Splatoon Gibberish Maker, a simple offshoot of the Animalese Generator by henryishuman and modified by Zach Coleman for Ren'py, made for quick and easy "dubbing" for Splatoon-related fanwork using undecipherable sounds.
Feel free to use for various projects. File includes audio files and tutorials with chapters to let you skip to a certain part. This was made in Renpy 7.4.11.2266, so if you want to put these files into your own visual novel, it may work but it hasn't been tested.
Also includes instructions to make it sound "underwater" using Audacity and other similar software.
