My memory is hazy, I do remember being one of the first designs proposed were for Apache and Turkey princess, the first is an obvious twist on that channer "attack helicopter " joke, makin the princess an helicopter aeromorph, despite what the joke implies and the tradition, she is not the trans/drag/ hermaphrodite princess of the gen, that title would be given to another princess.
If you've ever stumbled upon /trash/, you'll take quick notice of how full of fat and chubby related content it is, one of the concerns amongst the most puritan /tg/ regulars was the gen solely revolving about fat content, and while most folks did want to indulge in that, a compromise was met to have at least one, Turkey princess was conceived to fill that role, I don't remember whether she was created around thanksgiving or not but many liked the idea of a gluttonous Turkey harpy, bit of a fun fact is that, in each iteration of her being drawn, she is always way fatter than her original sprite.
