Use Your Own Pet
Import your own desktop pet look into PicoPaw.
Prepare a pet package
You can first read Download / Customize / Upload Pets to learn how to customize your own pet.
You can also download a ready-made pet from the gallery, such as a Codex pet, and prepare its compressed package.
Import it into PicoPaw
Right-click the small PicoPaw icon on your desktop and open the Appearance page.
At the bottom of the page, import your own appearance package. After import, the pet will use the new look.
