This Is a Poem That Heals Fish

　　Arthur's red fish, Leon, is sick. Arthur wants to help him get well, but he doesn't know what to do. His mommy advises him to give Leon a poem. Arthur asks his friend the baker, his grandparents, old Mahmoud, even his canary, what a poem is and each has an answer, but a different one! Is no one on earth able to explain to Arthur what a poem is? This can't be, because evidently it is just that--a poem--that will save Leon's life. Determined, Arthur decides that this is a mystery that must be solved!
