SuperJoe Does NOT Say Sorry

SuperJoe--superhero in the making--is far too busy to say sorry. He tears around the house sending invading space aliens back into orbit, rescuing passengers from sinking ships, and bravely facing prehistoric perils, while leaving a trail of broken toys, spilled bath water and displaced goldfish in his wake.

But one sound keeps interfering with his supersonic hearing . . . and that's the sound of his little sister crying. Can SuperJoe swallow his pride and say the one little word that will make everything better?
