|"Baby Kate's stuffed bunny" is not an official name.|
Shortly after her birth, Baby Kate was given a stuffed bunny as a present. The bunny has a pink bow and floppy ears.
- In Arthur's New Baby Book, the bunny is presented with holes where the ears would be, to allow the reader to stick their fingers through to pretend that they are the floppy ears. The bunny is also seen on the cover of the book, though in that image it has a blue bow.
