If you want to really get those preschoolers shrieking, read them Where’s Walrus.  There are almost no words, just a walrus they have to find on each page.  I didn’t realize exactly how amusing this book would be with our preschool class, but my goodness it was popular!  Walrus is hiding in very funny place, as a dancer, as a bricklayer, as a painter in a park.  That tricky walrus sure does know how to get children to laugh.  The illustrations are great, like cutouts, with beautiful, bright colors, grey, red, yellow and teal.  Highly recommended for young children.
