Points that the sphere cannot roll across and touch are safest from lightning.

A little later the sphere rolled to a halt and the bronzed man leant back, sighing with relief.

The sphere bobbed and rolled about; then a crack appeared in it, a jagged hole was torn in its surface, and a head protruded.

A sphere of ice-flower blue bolted from beneath the dissel thicket to the left and behind the gnome, and rolled toward him with incredible speed.

With bosoms bare, and bowed heads, and false looks Of true submission, as the sphere rolled by.

This giant bulletproof sphere can roll in any direction.

A massive sphere of energy rolled toward him, looking like fire with teeth, threatening to engulf him.

The sphere shifted and rolled as the last of the liquid dripped from the great gash in its side.

The white spheres touched and rolled apart.

He stood there, weaving slightly in the unsteady footing as the sphere rolled restlessly about in the beginning of its up-drive back to the surface.
