Calvin Babysits the Zoo

In a whimsical rhyme we learn that Calvin has been forced to babysit Mrs. O'Leary's zoo animals a monumental task that goes awry when all the animals leave the house to take a walk. Once outside singing and enjoying the summer sun the animals bump into Mortimer the mouse-and the chase is on. Bedlam of course ensues as the animals blaze a path of destruction through the city chasing the mouse while Calvin runs behind them yelling at the rampaging herd to stop.
