[Correction]

If you like the new bodies, your opinion is wrong!
And don't give me that "anatomically correct" nonsense! This is a cartoony video game containing turtle-like creatures with no arms.
The new bodies don't match the perspective at all. The game is a top-down perspective, which is why the old bodies appear short and squatty. The new bodies look more like a side-scroller perspective, and it just doesn't fit the surroundings.

Don't even make it an option! It looks bad enough to have the new bodies there at all, but then to have them mingled in with the old bodies would just be outright ridiculous!
And I agree with the others who have mentioned this - bring back the old hearts and drop this HP percentage crap.
