This is a prose fairy tale by Korney Ivanovich Chukovsky about the kind Doctor Aibolit, who 'will heal, will cure everyone.' It's based on a book by the English writer Hugh Lofting. The animals in it can talk. When they're in trouble, they come and flock from all over to a small house in the forest, where they'll be sure to receive help. And the doctor himself is ready to set off on a long and sometimes dangerous journey at the first call.
