What is "mtoto"

Mtoto (1 April 1983 – 24 May 2011) was a British Thoroughbred racehorse. In a career which lasted from 1985 until 1988, he ran ten times and won seven races. He showed some promise as three-year-old in 1986, but emerged as a top-class horse in 1987 when he defeated the Epsom Derby winner Reference Point in the Eclipse Stakes at Sandown. In 1988, he was the dominant middle-distance horse in Britain, winning a second Eclipse Stakes and taking the King George VI and Queen Elizabeth Stakes.
