I drew this yesterday for fun, might be something I do more often to be honest :3
He's about 7' tall, and has a capacity of 3000lbs of pressure, He's a little smaller than in the first picture when fully inflated, but can be inflated much bigger than even the last picture shows, due to his thick skin, which appears to be thinner in the stomach and thigh areas, though you won't see me complaining <3.
