Ferret doesn’t talk about itself in the first person. In fact, Ferret can only quote things it finds on the internet. Purple and Nine made Ferret accidentally when trying to create a chess piece on a 3D printer, as you can see in the pilot episode of Purple and Nine. (link) So far, Purple and Nine have managed to keep Ferret hidden from everyone.
When inspired, Ferret brings the girls all kinds of inventions from the Internet. Most of them are junk, but that’s how it goes when you search for things on the Internet. As far as Ferret is concerned, there’s no better way to spend the afternoon than trying a pile full of inventions to see if any of them are useful.
