Feet on the Floor

Whoa! Green Hill... wait, where is the grass? This place is just totally white. I blinked, and my elbow clicked—hey, I moved it myself! I shifted my weight, tapping one red shoe against the pale, hard floor. Tap, tap. The ground is completely solid. No loops anywhere, but my joints bend just fine. I raised my hand, curled my fingers into a fist, and looked around. No monsters yet, just quiet space. Wherever this blank zone is, my legs work, and I'm ready to move!
