I liked the book because it was hilarious. I laughed when they sang, "We are monsters, we are tough, we don't take nobody's guff." My favorite part was when they saw the three-headed dog. It was funny when they taught the three-headed dog tricks. This book reminds me of last year in the science fair. We made time-machines that would take us back a long time ago just like Fred, Sam and Joe.
I recommend this book because it is it is hilarious. Second grade and up could read this book.
