Heikens Ark Jupiter, aka Humphrey, was purchased by the Gardner family of Kelona in May 2017, and it was only after buying him that they discovered he wasn't a calf, he was a fully-grown 3-year-old miniature zebu bull.

"Most people, when they think of a bull, think of a large animal and he is not that by any means!" Humphrey was officially measured by a veterinarian at 26.6 inches tall, 1.5 inches shorter than the previous record holder, a California bull named Chegs HHAR Golden Boy.
