(his full name is Sergei Alexander Bobinsky, and friends call him Mr. B.), one of Coraline's neighbors. He is a blue-skinned Russian giant who once trained as a gymnast and lives on a steady diet of beets. While not explained in the film, his blue skin may perhaps be due to his time as a Chernobyl Liquidator, for which he wears a Liquidator medal on his sleeveless shirt.[6] Coraline's mother believes him to be a drunk, but Coraline points out that he's just eccentric. The Other Bobinsky is the ringmaster of a circus of rats disguised as jumping mice, and later exists only as a coat filled with rats.
