Doctor Aybolit
Doctor Aybolit is a fictional character from the children's poems Aybolit (1929) and Barmaley (1925) by Korney Chukovsky. He is a kind and compassionate doctor who travels to Africa to help sick animals. He is often accompanied by his animal friends, such as the Pushmi-pullyu, a creature with a head at each end of its body. Aybolit's antagonist is the evil pirate Barmaley, who kidnaps animals and holds them for ransom. Aybolit has become a recognizable feature of Russian culture, and his name is often used as a catchphrase to express gratitude or relief.
