The Round Mirror Trap

I walked into the kitchen to find more dangerous things to crush. On the counter, a warrior was standing inside a flat metal ring. It had white armor, red knees, and a sword, just like me. It pointed its sword at me. I pointed my sword at it. It was very brave. I charged forward with a mighty battle stomp. My sword hit its sword with a sharp clink against the shiny glass. It copied my exact battle shout, but silently. Then I backed away. It backed away too. It is clearly terrified of my power. I left it trapped inside the round metal disc.
