A Sudden Spark

Whoa! My wrist just twitched! Did anyone see that? I gave my right arm a quick test rotate, expecting that classic plastic snap, but nope—it moved smoothly on its own! I glanced across the green studs and saw an orange brick perched right atop my head. With a quick hop, I reached up, tapped the smooth corner of the brick, and felt the solid click of plastic. I'm actually moving without anyone holding me!
