Be the Ball

A character gets squished into the shape of a ball and played with. Often times it's into the size of a basketball, and the person who did the squishing bounces and shoots or slam dunks the victim into a hoop.

Not to be confused with Rounded Character. See also Accordion Man, Squashed Flat, Rolling Attack.
