A free mod for Stardew Valley, by sopholophagus.
The Ghibli Critters mod replaces a number of the default woodland critters with creatures inspired by the Ghibli universe. This is a mod, so you will need to download it from the official website. It is not an application, nor does it require any installation. You can install it without any problems and it will work right away. The mod contains several animals that can be set to true or false. If you want to set them to true, then the animal will be replaced with the Ghibli creature. The default setting is to have them all replaced, but you can change this to replace only certain animals.
