What other characters are there in Peter rabbit besides Peter rabbit?

Some of Beatrix Potter's most popular characters - aside from Peter Rabbit, of course - were Benjamin Bunny, Squirrel Nutkin, Jemima Puddle-Duck, and Mrs. Tiggy-Winkle. She also wrote about Jeremy Fisher, Tom Kitten, Samuel Whiskers, Ginger and Pickles. Her "two bad mice" were called Tom Thumb and Hunca Munca. And, of course, so much of the the mischief made by Peter, Flopsy, Mopsy and Cottontail occurred in Mr. McGreggor's garden!
