I had an invisible dog named Masalit. I didn't know how to pronounce Maltese (a kind of dog, which I saw in a book once), so I just said Masalit. She walked on two legs, and had a blue bow on her head. She was only about three inches tall.
Over the years (yes, years... I think I was five or so when it started, but she lasted until I was almost a teenager), Masalit got friends. There was Wolfy the wolf, Foxy the fox, Coyot the coyote, and Bloody the bloodhound. I don't remember why I stopped playing with her...
