She deffinalty looks like an obese jungle. When snake are really obese they start to get blobs building up on their side which it looks like yours is developing that.
WHen jungles get older they loose a lot of their color. Most people don't know that when they get a nice bright hatchling. SOme can reatin it but most do get duller. I have one that isn't amazingly colored but very nicely colored for it's age.
$90 is a smoking deal, as long as it doesn't die early because of health issues from being overweight. Because of her weight even cutting her feeding down more then a med every ten days would be good. A med every 2 weeks and mabey skipping to 3 weeks every once and a while could help till she gets to a better weight.
