BoJack is an adult, male, grade/thoroughbred cross horse. He is around 6'7" feet (15.2 hands at the withers, 19.75 at the ears) tall. During this time, BoJack is slimmer and has a longer, thicker mane that somewhat resembles a mullet. He has brown (medium bay) fur, with a white snippet on his snout that begins at his upper lip and ends underneath his eyes, a white diamond-shaped mark on his forehead, and a pink spot on his nose. Despite being a horse, BoJack, like other animals in the BoJack Horseman series, has a humanoid body, and is designed with human feet and hands and does he not have a tail. He wears an orange sweater with pink apples along the middle and a pink collar and cuffs, along with light blue jeans and red and white sneakers.
