Old MacDonald had a farm like you've never seen before! With a nod to the familiar refrain E-I-E-I-O, a day on this farm is framed by the vowels A-E-I-O-U--and sometimes Y. Old MacDonald appears in an explosion of color and, starting with the letter A, proceeds to saw barn planks, stack sacks, crank cranks, and whack gnats. The day progresses as every vowel is featured in action-packed bursts of lively text. Old MacDonald has devised a myriad of tools to make her job if not easier, then a lot more fun. In chaotic scenes filled with pulleys, catapults, and flying machines, the farm becomes the background for a circus-like riot of fantastic contraptions. With dozens of details to discover, and hilarious tongue-twisting text, this book is destined to become a favorite.
