How does this stanza from "The Walrus and the Carpenter" contribute to the meaning of the poem? The sun was shining on the sea, Shining with all his might; He did his very best to make The billows smooth and bright— And this was odd, because it was The middle of the night. It introduces the nonsense tone of the poem. It expresses the deeper theme of the poem. It describes two of the main characters in the poem. It advances the events of the story.
