Bobo & Pup-Pup find something that they think is an egg, and then they try to hatch it. But is it really an egg? Will it hatch? What will come out if it does? Readers are in on the joke as the two friends go to increasing lengths to hatch their "egg". Look for this book everywhere books are sold! Appropriate for ages 4-8 and can be read to 2-3 year olds too!
