Upon meeting the two little fat men, Alice quotes the nursery rhyme, which the two brothers then go on to enact. They agree to have a battle, but never have one. When they see the Crow they take to their heels. The Tweedle brothers never contradict each other, even when one of them, according to the rhyme, "agrees to have a battle". Rather, they complement each other's words. This may have led to Tenniel's depiction of them as though they are twins and identical in physical appearance. According to the dramatis personae for Through the Looking-Glass, Tweedledee is the White Queen's rook and Tweedledum is the White King's rook.[2]
