And, I suppose, to keep Disney's G to PG rating. Can't really market a movie to kids and show animated titties, now can you? Also, she's only 16, so there's that.
Then again, why is Ariel only 16 to begin with? I get that she's a teenager in the source material, but it's not like Disney has never taken artistic liberties. And it's not like 18 year olds don't deal with power struggles with their parents. I was having power struggles with mine at 22.
Well, I just found out that manatee mammaries are located in their armpits, so I think we're going to need to pull up the drawing board on this one. Seems like mermaids need a total do over!
