Yeah that too
Although I don't find that quite so sinister.

Apparently the animator thought that udders looked funny. I have issues with female secondary sexual characteristics being thought inherently amusing, but leaving that aside - why not make the lead character a female if you want them to have amusing udders?

A female lead character?
Conservative Americans would go crazy! What sort of message would that send to the children?

EXACTLY
and then you couldn't have sinister girl-cows with udders, chest swellings roughly where human breasts would be, earrings and a sidekick role.

udders and boobs, eh?
reminds me of pottery classes in school when we were making birds, and were explicitly told not to do a mouth underneath the beak, because that's just stupid. But apparently that's quite a common mistake otherwise.
