There’s nothing much more fun than playing in a giant cardboard box. I remember as a child receiving an enormous Playskool kitchen set for Chanukah and having a lot more fun playing with the packaging it arrived in (no offense to Playskool–that kitchen set was awesome, but I unfortunately have never been much of a culinary artist). Dee Lillegard captures the excitement of letting your imagination run wild in Sitting in My Box, illustrated by the great Jon Agee. In the story a little boy is sitting in his box, reading a book about jungle animals. The animals suddenly begin to present themselves, asking him to make room, until he’s sharing the box with a giraffe, elephant, baboon, lion, and hippo. The box is getting a little overpopulated, but a pesky flea plans to change all that!
