If you're a huge fan of plush toys and internal organs (and who out there isn't?), then there was really only one booth for you - I Heart Guts. In addition to plenty of cuddly goodies, they also had t-shirts with the same wittiness of their plush line.
Booth Favorite: Bladder Plush
Well...I had to choose one organ, right? And while sweat glands would have been a perfect choice for Comic Con - they haven't created an I Heart Guts sweat gland yet. So...the second most distinct smell at Comic Con - urine - is stored in the bladder. (actually, urine might be third to fried food)
