What is the mood of the walrus and the carpenter?

The mood of the Walrus and the Carpenter in Lewis Carroll's poem is both whimsical and somewhat somber. While they engage in playful conversation and enjoy a stroll, their actions towards the oysters reveal a darker, more sinister undertone. The lightheartedness of their dialogue contrasts sharply with the tragic fate of the oysters, creating a sense of irony and moral ambiguity. Overall, the mood is a blend of joviality and underlying menace.
