Keep on Knocking! Unique-shaped 300-piece jigsaw puzzle for ages 10 and up.

Each puzzle comes with an educational Madd Capp Fun Facts booklet. On one side is a fold-out puzzle image to hang as a poster or use as a reference. On the flipside is a wealth of amazing facts. Did you know, for instance, that most woodpeckers have a flight pattern - a few quick flaps, then a glide, with their wings tucked up against their body?
