In a big field, a boy has a tree house, and one day, he has a neighbor—a monster with a talent for silly dances and funny faces. The two become fast friends, even setting up a pulley line to pass notes between their tree houses. The boy knows just how to celebrate this invention—with music! But the monster’s tuba music is loud. Really loud. WAY. TOO. LOUD. Before the boy can think, he hurls a water balloon at his neighbor to get him to stop. An epic water-balloon fight ensues, until the boy—fed up, spent, done—cuts the pulley line. No more note-passing. No more monster. Can the boy and monster ever be friends again? Does the boy even want to? Maybe he just needs to see things from a new, unexpected perspective.
