2015 год. Random House USA Humphrey can't wait to spend the weekend at Heidi's house, because she is planning an adventure--a backyard camping adventure, to be precise!-- with some of the girls in Humphreys' class. Backyards can be very exciting places when you're a very small hamster. There's a s'mores roast, ghost stories, and an expedition to hunt for creepy crawly creatures. But the prank-loving boys next door are determined to prove that the girls are scaredy-cats. Fortunately, Humphrey knows better--and he proves it with a prank of his own!
