Not as much as he loves his new physique. Applejack has become completely enamored with his bulgy biceps, pecs, and abs, loving the raw power and girth displayed in them. He especially loves his new junk as well, having plenty of fun with that on his spare time.
Yet, there's someone else in the farm that isn't as impressed with the new stud walking around, his younger sister, Apple Bloom. The young mare just doesn't get Applejack's strange obsession's with his form or even wanting to be a big stallion. It's honestly a bit embarrassing and gets her a tad flustered every time she finds her former sister macking or posing in his mirror. What was so great about being so buff and manly?
