Sphere Factor

Let's hope they don't roll through poop.

Characters using a large, spherical or cylindrical object as transportation and/or a weapon, whether by rolling or bouncing. They may use it by being inside or on top of it.

Sub Tropes include Floating in a Bubble. Compare Rolling Attack when the characters move like a ball/wheel and Be the Ball for when they are the ball. Also see Monowheel Mayhem when the characters are inside a large wheel.
