The character is a living disembodied head. Unfortunately, this means they don’t have a body and aren’t up for running, playing tennis, or much of anything else. They cannot move themselves, and cannot manipulate objects except with teeth. The upside is that they’re exceptionally portable. They now fit inside a large lunch box or a bag designed for carrying a bowling ball. Also, someone can easily carry them while running. Unfortunately, that also includes someone who wants to steal them.
