Kids can join happy dogs Yao and Rico as they try to make the perfect birthday cake for their friend Oppenheimer. While helping count the ingredients, kids can use their fingers to trace the cut-out of each number and count the cut-out dots. The book includes a guide for the parent or caregiver. The Great Cake is coming in July 2006. Also in the series are Moo, Moo Who Are You? Hide & Peek and Imagination Vacation.
