Make them flip, make them flop, make them roll on the floor...These are books that really move! These 4 zippy board books have wheels attached--and the animals' legs go 'round and 'round while their heads bob up and down! So while kids read the story about animal movement, and look at the colorful artwork, they can make duck, penguin, pig, and tortoise do everything they see in the pages. Penguin flaps, slips, slides, and dives. 10 pages (all in color), 4 1/8 x 8 1/4.
