A favorite ursine returns, this time squirmy and impatient. Bear's den is strewn with colorful streamers and presents. Bear himself wears a jaunty polka-dot bow tie. He is excited for a surprise, but it's not happening until later. "He looks toward the sun, / but the day's just begun. // But the bear / can't / wait!" Gopher, Mouse, and Mole stop by with ingredients for a carrot cake, and everyone joins in mixing and measuring. "Raven brings a candle / and Owl brings flowers. / Bear asks, 'Is it time?' / But there's still TWO hours!" Bear starts to get even more antsy. In true preschooler form, he starts to fidget and wriggle, tangling the decor around him. Then, when he rushes to be the first one to help with the cake, he trips--and the cake is squashed! All "because bear / couldn't / wait!" Suddenly, Bear's speedy (yet, this time, controlled) tendencies are needed as everyone puts the party together again. Impulsive tots will relate--patience is a difficult skill to grasp. Wilson's sturdy, familiar verse steadies the story, even amid the flying frosting. Chapman's equally familiar cute forest animals are as expressive as ever, and Bear's postures as he struggles to wait will elicit both giggles and sympathy.
