Sinna Bhagudori is one of the "smart girls" who attends McKinley Elementary School. Sinna is one of Eliza's competitors in the school spelling bee. Eventually, Sinna becomes a friend of sorts to Eliza Naumann. At the beginning of the narrative, Sinna is described as having "blue contact lenses and big boobs" (p. 7). Even though the other pupils at McKinley know that Sinna's eyes are not really blue, Sinna, who is obviously of East Asian descent, "insists that a lot of people's eyes change when they go through puberty" (p. 7).
