Amelia Bedelia is heartbroken to miss her class field trip to the zoo. But then Amelia Bedelia gets an amazing idea -- why not design and build her own zoo in her backyard? She invites her friends to help (and bring their pets) and soon she has a snake, a cat, a gecko, a mouse, a sheep, and (of course) a puppy, as well as loads of other great exhibits and rides. Now, if only she can find the adorable squirrel monkey that escaped from the city zoo and is on the loose in her town!
