In The Flopsy Bunnies, Benjamin Bunny and his cousin Flopsy are the parents of six young rabbits called simply The Flopsy Bunnies. The story concerns how the Flopsy Bunnies, while raiding a rubbish heap of rotting vegetables, fall asleep and are captured by Mr. McGregor who places them in a sack. While McGregor is distracted, the six are freed by Thomasina Tittlemouse, a woodmouse, and the sack filled with rotten vegetables by Benjamin and Flopsy. At home, Mr. McGregor proudly presents the sack to his wife, but receives a sharp scolding when she discovers its actual content.
Modern critical commentary varies. One critic points out that the faces of the rabbits are expressionless while another argues that the cock of an ear or the position of a tail conveys what the faces lack. One critic believes the tale lacks the vitality of The Tale of Peter Rabbit which sprang from a picture and story letter to a child. Most agree though that the depictions of the garden are exquisite and some of the finest illustrations Potter created.
The book includes original illustrations by Beatrix Potter.
