A chapter book series about a young bulldozer who is nervous about making friends and starting school by the award-winning team who created Masterpiece. Bulldozer is shy when it comes to making new friends and nervous about starting school. But when he meets his new neighbor Millie and her little brother Jay, Bulldozer embarks on a daring adventure to rescue a stranded cat. With the help of his own machinery—and a plate of freshly baked cookies—Bulldozer overcomes his fears just by being himself. The beloved team of Elise Broach and Kelly Murphy are back with a compelling new series about an endearing bulldozer living in a human world. Each book contains five chapters, perfect for emerging book explorers learning how to take on books on their own.
