Books in Zig Zag series

Help find the missing items! In this accordion-style book, simple story lines contain characters searching for missing items and each story leads to a hidden frieze at the end of the book, where all the objects are revealed on one colorful fold-out. In Trucks, different toys are waiting for a variety of trucks to help them with their work. Farm animals are waiting for a tractor to bring them their hay, but the tractor is nowhere to be seen, and some construction workers are waiting for a digger to dig up the road, but the digger is missing. At the end of the book, children pull out the accordion pages, and find all the missing trucks stuck in a traffic jam!
