トニービン
Jungle Pocket was is a bay horse standing 16 hands high with a narrow white blaze bred in Japan by Northern Farm. He was sired by the Irish-bred, Italian-trained Tony Bin who won the Prix de l'Arc de Triomphe in 1988 before being exported to stand as a breeding stallion in Japan. Tony Bin's other progeny included Air Groove (Yushun Himba, Tenno Sho), Lady Pastel (Yushun Himba), North Flight (Yasuda Kinen, Mile Championship), Telegnosis (NHK Mile Cup) and Sakura Chitose O (Tenno Sho). His dam Dance Charmer was an unraced daughter of Nureyev. The colt raced in the ownership of Yomoji Saito and was trained during his racing career by Sadao Watanabe. The horse was reportedly named after an episode of the NHK Children's television series Okaasan to Issho.
