Frog Legs: Stanley is less-than-excited when he learns that he's finally old enough to join his family in the big pool. In fact, he doesn't want to admit it, but he's a bit scared. When he states that humans are meant to stay on land, Dennis mentions an animal that copes quite well on both land and water-- the frog. Stanley decides to find out more about this animal by hopping into The Great Big Book of Everything. Whoo's Afraid of the Dark?: Stanley and his pets all want to get to sleep, but Stanley keeps hearing mysterious noises. His mom assures him that there is nothing to be afraid of, but Stanley remains convinced that he's hearing a scary monster. He knows that owls can see in the dark and wonders how they do it. He seeks the answer in The Great Big Book of Everything in the hope that it will help him to spot the monster so everyone can finally get some sleep.
