I mean, amorphous creatures are literally defined by not having a fixed shape. Working out what skinny or fat in their context would be practically impossible.
You cut my paragraph in half, so missed the point.
All of it, glasses, legs, skinny was about the slime monster. You can not apply human aspects to non humans.
"Humanoid" is just the outward appearance of other PC races. It does not mean their physiology is identical. Vampures regenerate, why would they need glasses? Interbreeding of PC races is silly, unneeded in the game. Maybe Elves do not have "fat". This is all setting defined, and not even getting into saying dead weight in a combat is not going to work too well. There was in the past the wizard considered dead weight as after expending spells, the adventure was on pause until it rested to regain spells and not be useless. How does this work scaling a wall with soneone extremely over weight that everyone else must hoist their petard over?
To borrow from Men in Black, adveturers should be the best of the best of the best, and art should represent the adventurer, not the gluttonious land baron overtaxing his citizens. Not in the PHB at least, nor the monster manual. Robert the Glutton, should appear as art in his adventure to show players.
To borrow again from recent fiction, "to escape the zombies, you don't have to be the fastest you only need to be faster than the next guy."
It is not about depicting what a player would look like, but what a PC should look like in its environment. D&D does not have the football so Bill the technician sit in NORAD eating Dunkin all day waiting to push a button to send the launch code approval. It has "people" that must be in decent form to actually survived.
