There was once an old woman who raised rabbits of all shapes and sizes, and would sell them on a street corner to buy cabbage, and bread. She had so many rabbits, as they bred so fast. The rabbits were all white, with pink eyes. And Bumper, had the whitest, with the pinkest eyes. The old woman takes Bumper, and some of the other rabbits to the street corner, and tries to sell them. A little girl ran over to the woman, and saw Bumper. She fell madly in love with him, but couldn't afford to buy him. But the interaction with the little girl brings up questions with Bumper. Questions about his existence, where he came from, why he and the other rabbits all have the same white fur, and pink eyes. He also begins to question why people buy his brothers and sisters, but not him. Soon, that will change, when a woman comes looking for a pet rabbit for her young son. He eventually goes on a great many adventures - investigating vegetable gardens, discovering sewer rats, and meeting all sorts of friends, like sparrows, and foxes.
