The tag implication #66385 anatid_penis -> animal_penis is pending approval.

Reason: Wiki says: "A penis that resembles that of anatids, such as ducks, geese, or swans."

Do anatids largely all have similar looking penises? If so, perhaps duck_penis, etc, should be aliased to it, like how wolf_penis and fox_penis are aliased to canine_penis. Or if they aren't similar, I don't think it's useful to have tags that are just x+penis and says little about how the penis looks (e.g. we don't have a mammal_penis tag for any mammalian penis, because it's not a visually distinct type of penis in and of itself).

I feel like this should just be a direct alias request from duck_penis to anatid_penis which would drag the animal_penis implication with.
