No one knows why Harry is wearing a necklace. Sidney thinks they're for girls. But when Harry opens the necklace cover to reveal a mini-microscope, the whole class is intrigued. Everyone wants to try it, so Harry promises to show them all some wicked-looking fungi at recess. But he doesn't mentiom that to see them they'll need to go outside the fence-and that means breaking a school rule. Will everyone follow him? What if Miss Mackle finds out? Has Harry gone too far this time?

          I did not like this book. This book includes Harry lying about something.If you do not like books with a liar or an gross person I wouldn't recommend this book. The Book was about Harry going outside the school at recess with his friends one by one to see a mushroom but when the bell rings and they have to go to the class there is mud on the floor and Harry tells a lie saying that the mud gremlins did it.The Mud Gremlins is a lie.
