Two Thumbs and a Tap

Ooh! My thumbs were locked pointing up, stiff as little pegs. A squeak popped out of my chest—hic!—and suddenly my left thumb twitched. I wiggled it, then curled both hands together into tight fists. My wide bare feet felt the ground below me, and I did a tiny bouncy hop on the patterned surface. Patter-tap! I am moving, fully bouncy and ready to explore!
