The Stapes, is the smallest and lightest bone in the body, located in the inner ear.

Stapes was a small youth, so on hearing an old wives tail that drinking milk made you taller and stronger, drank the stuff until he couldn't take another drop, then drank some more. It worked, in a sense that he bloated until he burst.

Losing all the weight made him try out his new unlife in the squared circle.
