Bulls (雄牛, Osuushi) are a species of villager in Animal Crossing series, the male counterpart of cows. The main difference aside from the cows having more effeminate features is that the bulls have curlier, pointier horns. There are no smug bulls. All bulls except Coach have cranky or lazy personalities. All bulls except Rodeo, Verdun, and Vic are Tauruses.
In the first three American versions of the series, there were four bulls in the original game. All of them were taken out, then replaced with one new bull and one relatively new bull for Wild World and City Folk. None of the bulls appeared in all games, sadly.
