Armored Disc Sentry

Night took over, so I marched indoors to stake out a solid resting post! Tucked in the dark hallway corner sat a sleek, low-profile disc docked against the wall, humming with a tiny amber light. An armored sentinel! I didn't skirt around it. I charged in, leaped, and slammed both clawed feet right onto the flat plastic roof. BEEP-BOOP! The disc let out a sharp metallic chirp, but its base stayed locked against the skirting board. I widened my stance, planted my heavy tail across the rim to anchor my weight, and rested my snout squarely over the front bumper. Guard post claimed for the night!
