Bizzy and Dill decide to celebrate Opposite Day by spending their time doing the opposite of what they usually do, including starting with dinner instead of breakfast, wearing their pajama pants on their heads instead of their legs, and singing a book and reading a song. Bizzy the strange bird has decided: Today is Opposite Day! Time to eat dinner for breakfast, have a loud dance party instead of a quiet rest, and say good morning at bedtime. But Bizzy's best friend, Dill the odd duck, would prefer to have a normal day, with no opposites. So Dill says, "No, no, stop!" to Opposite Day, while Bizzy says, "Yes, yes, go!" Will Opposite Day turn best friends into worst enemies? This playful picture book combines an original introduction to the concept of opposites with an eccentric but heartwarming friendship story. If today is truly Opposite Day, be prepared to hate this book!
