too picky?

Would anyone care to explain why all of the males in the new movie "Barnyard" have UDDERS? I double checked- this character's name is Otis and his voice is done by Kevin James so it's supposed to be male..... It just goes to show that boobies win over penises any day of the week.

PS- it looks like all the other animals have nice smooth Barbie-like under parts. Only the cows have odd gender issuses.
