Rumble! Clank! Clunk! The noises of a busy construction site come alive in this illustrated board book with four sound buttons. In Blippi: At the Construction Site, YouTube sensation Blippi is on the scene, driving an excavator, a dump truck, a backhoe, and a bulldozer. He's so excited that he even invents a dance or two for some of his favorite vehicles--kids will want to get up and dance, too!
