A Big Fist Shake

Oof! Whoa! My stiff arm suddenly surged with real power! I clamped my fist tight and gave a mighty upward punch into the empty air. My chest puffed out, my toes wiggled, and a warm hum rattled all the way through my plastic joints. I took a hard tap right against the smooth wooden door trim beside me—thud! Strong, solid wood! Ha! I'm completely alive and ready to smash!
