How the Mouse Became a Fly (1991)

Each of us has dreamed of something at one time, and this little mouse is no exception. From early childhood he had only one cherished desire, although he never thought that it could come true. However, after meeting a pig and an ostrich, who were incorrigible dreamers, he began to have hope. After all, his new friends also dreamed of something unattainable, and they made incredible efforts to make these desires come true.
