Henry Hedgehog loves the sights and sounds of fireworks. He also loves birthday balloons because when they pop they sound like fireworks exploding. This 4th of July he comes up with a plan to pop the giant red white and blue balloon near the fireworks stand. This balloon is different because it has lots of smaller balloons inside but what Henry does not know is that the smaller balloons are filled with water. What will happen when he pops the large balloon? Pippi the black and white poodle who lives with the owner of the fireworks stand knows about the water balloons. Will he warn Henry or will he let him find out for himself about the water balloons? Clive the big orange cat who lives next door to Henry also loves to pop balloons. What happens when the two friends join forces to pop the big balloon? Will the water balloons pop and get both of the pranksters wet?
