I literally have no idea where this came from. it literally makes no sense.

1 Mario Physically can't get fat. because he's jumping around all the time saving Princess peach

2 he plays a lot of sports

3 he doesn't even look fat. and sometimes he looks like he's the opposite of fat

4 have you seen gameplay of Sm64 or sunshine?

sorry if this comes off as annoying just don't like when people don't understand characters I like. I have nothing against headcanons. I have some myself, but they have to at least make sense.
